Have you ever owned a monogrammed towel or some other item with your initials on it? Or maybe you have a sign on your mailbox or your front door sporting your family name. We humans tell the world that something belongs to us by attaching a label.
Many dogs also like to advertise that a certain object or place is theirs. However, the doggie way to proclaim ownership doesn’t involve labeling — it involves scent, specifically urine.

Urine marking is a challenge for dog parents to deal with. Unlike simple accidents, which may indicate a need for some further housebreaking or more frequent potty breaks, urine marking is territorial behavior. It can be more than a little baffling when a completely potty trained pooch is still peeing on things in the house.
Thankfully, there are things you can do to change your dog’s habits. But before you take steps to deal with your dog’s urine marking, you should check with your vet to rule out any possible medical causes for the behavior. Conditions like bladder or urinary tract infections can cause a dog to urinate frequently and need to be treated promptly.
Why Do Dogs Urine Mark in the House?
Dogs are not spiteful or vindictive, so urine marking is never a sign that they are trying to “get back at you” for something. Instead, it’s usually brought on by something that they perceive to be a threat to their territory. Here are some of the most common reasons for urine marking:
- Not being spayed or neutered. Although it occurs much more frequently in males, some females will also mark their territory, especially if they are “unaltered.” At times, even spayed or neutered dogs will urine mark in response to an intact animal in the home.
- Unfamiliar objects in the house. New (or new to you) furniture, carpeting, or even a guest’s jacket or purse may trigger the need to mark — especially if they carry the scent of another animal.
- New people in the house. A new roommate, significant other, or baby may trigger urine marking. Putting his scent on things that belong to them is a dog’s way of reminding them that the house is his.
- Establishing dominance. If he’s in conflict with another dog, or even a cat, your dog may be having trouble establishing his place in the pack. He might begin marking his territory as a way to gain the upper paw.
- Contact with unfamiliar animals. Hanging out at the dog park, encountering other dogs on walks, or even seeing other animals through the window can cause some dogs to mark their own territory.
- Anxiety. In some cases, new objects or people in the home, furniture, luggage, or conflict with other animals or people could cause anxiety that leads to urine marking.
How to Stop Your Dog from Marking in the House
Depending on the reason for your dog peeing in the house, one or more of these approaches may be the right one for you. With patience and persistence, you can stop your dog from marking inside.
- Spay or neuter your dog. This will reduce or eliminate urine marking in many dogs. As many as 50-60% of male dogs stop urine marking, or at least do it significantly less often, after being neutered. If your male dog is peeing in the house even after he’s altered, there could be other behavioral or physical issues that need to be addressed.
- Talk to a Certified Veterinary Behaviorist about how to resolve dominance issues between pets. Dogs marking in the house is often about territory, so there may be some hidden (or obvious) signs that your dog is feeling the need to compete. You can find a Veterinary Behaviorist here.

4. Try a synthetic hormone diffuser. These have a calming effect on some dogs and can reduce the urge to mark. I love this one from Adaptil! It comes with the diffuser and a 30-day supply.
5. If your dog’s marking is caused by anxiety, check out our pet anxiety resource page, and be sure talk to your vet about ways to treat it.
6. Limit your dog’s ability to see animals outside. If you can’t block access to windows or doors that allow him to view other animals passing by, you may be able to discourage them from approaching your house.
7. Keep your dog away from areas where he has marked before.
8. Change the meaning of the place where he tends to mark. Leave treats around and feed and play with your dog in the area he marks — he’s less likely to continue marking there.
9. If his marking is in response to a new person in the house, have that person make friends by feeding and playing with your dog. If the new arrival is a baby, give your dog lots of treats, toys, and attention when the baby is around.
10. Establish yourself as the pack leader. One way to do this is to teach your dog basic commands such as “sit” or “lie down” and then have him obey one of these commands before he’s fed or taken for a walk.
11. Move objects he has marked so that they are out of reach, and keep guests’ belongings and new purchases safely stashed away.
12. If your dog’s marking is caused by anxiety, check out our pet anxiety resource page, and be sure talk to your vet about ways to treat it.
What Not to Do When Your Dog Pees in the House
If your dog is peeing in the house, never punish him for it, even if you discover it after only a short time. He won’t make the connection between his actions and your disapproval, which could lead to confusion or fear. However, if you catch him in the act, it’s okay to take actions (such as loud clapping) to discourage him from continuing.

I have 2 unaltered male dogs. One is 13 and is the father of the 1 1/2 yr old. The younger is challenging the older for the dominant position and their marking inside is really getting old. Besides neutering, how can I help the transition of the dominant male or keep it established w the older dog? We also have 2 spayed females in the household, the mother, 4, and the sister to my male, 1 1/2. The mother dog is also a dominant female!! They all wait for the younger female to potty and then all 3 Mark it!! It’s a crazy household!! Please give some suggestions!! Thanks in advance!!
Oh my goodness! You have a lot on your hands Kelly! I assume you do not wish to neuter the males? Because that would be my #1 recommendation. Do they mark the same places? Or different ones all the time? If the same place, it could be because they smell it from before and continue to “refresh” the scent marking. An intense cleaning of those areas with a bio-enzematic cleaner could help. But my gut tells me this is a complicated behavior problem that would best be addressed by a veterinary behaviorist. Here’s a link to help you find one near you. Keep me posted. I hope this helps Kelly! You must be so frustrated!

I have a question, my puppy is 8 months and before we used to go out he used to take a long pee, now all he does is mark many places outside but doesn’t take that long pee. Is this normal ?
Thank you
Hi Jude,
It sounds like he is marking his territory. This could be due to an environmental change. If he is only making outside, it is possible there have been other animals in the area marking in the yard, too. So, naturally he goes and marks his territory in those areas. As long as he is getting all of the urine out, and he is not marking inside the home, it shouldn’t be something to be too concerned about.
Hope this helps!
Kristen
I need help!!!! I have a 2 yr old male Yorkie that is a rescue. He marks more than normal. And I don’t know how to stop him. He is now getting on my table and marking in the middle of the table.

Sir I had a pomeranian 5 month old when he saw a a Street dog lifting his leg and then he also began. Now he has been 10 months he is marks on the walls . I am fed up of his behaviour.
He is not not neutered.
Pleaseee help
Rajni,
If you have him neutered there is a good chance the behavior will be reduced — possibly even eliminated.
Good luck!

I have a two year old min pin Pomeranian and he is fixed and yet he pisses on everything. It don’t matter what it is. Then of course the older and bigger dog piss where he pissed. It is getting so old. What can I do?
I have a daschund and a pug and the pug keeps jumping on my sons bed and weeing and it’s really getting annoying! What can I do he isn’t done as he is still u der one and my daughter (his dog mum) doesn’t want him doing yet? Heeellllpppp!
Hi Diane,
It’s perfectly safe to have him neutered under a year old. But if your daughter wants to wait, I understand.
Regarding the pug weeing on your son’s bed, is this the only place he goes? If so, a temporary fix would be to restrict his access to the son’s room. It’s hard to know for sure why he’s marking your son’s bed. It could be a territorial behavior as you have another dog.
Sometimes dogs mark due to a health issue or due to anxiety. I’d suggest you take him to the vet to rule out any medical issues that could be causing or contributing to the behavior. The veterinarian can also determine if anxiety may be a factor.
Good luck!
Kristen
Hi Sarah!
Yikes, you poor thing! No it’s definitely NOT too late to neuter him. As a matter of fact, that might stop the behavior all together or at least reduce the marking.
It takes a few weeks after a dog is neutered for you to see the difference, so I’d book the appointment today!
I would also talk to the vet about the problem so he/she can examine him and do diagnostics to rule out any medical issues that could be causing the behavior.
I hope this is helpful! Keep me posted.

I have a 20 month old Shihtiz. He has been neuter. He still hikes & pees on my furniture or anything that is in the floor. He will pee in my kitchen & bathrooms. It’s just me in the house no other dogs hike here. I have asked the vet & he said they get it from a family member. It’s just about to drive me crazy. I am a clean nut anyway & I just don’t know what to do. I have pads down for him. What would help me please I need it. Thank you
Hi Linda,
I’m sorry to hear of your struggle with your pup marking in the house!
Some dogs urine mark due to anxiety. I would try getting him a pheromone collar like this one: https://amzn.to/2Pmj37G. You might also try limiting his access to certain areas of the house, especially those where he’s marking a lot.
Keep me posted!

Hi I have a 6 years old shitzu mix he pees everywhere in my house I always have pads in the house but in a certain area so he can just pee there but the pads are always dry I’m going crazy because is getting out of hands I started adding pads everywhere in the house but I don’t know if it is a good idea please help me
Hi Josie!
Oh gosh, that is difficult! Is he neutered? That would be my number one recommendation since neutered males are much less likely to mark. Additionally, puppy pads can be good for training and to help with accidents, but when you use them all the time it can cause dogs to think it is okay to pee inside. So, if you notice him peeing on the pad, take him outside as soon as he is done to help redirect the behavior. Also, clean the area well after he goes so he can’t smell the pee anymore. That will help him to not go there again. This is the cleaner that I use: https://amzn.to/32m14pk and I love it!

Hi we have a neutured male Jack Russel. He has been great with our cat in the house but sibce we bought in a rescue cat he has started marking. Up against my drapes and on brand new carpet. Up against my washing in a basket on the doors. On the tiles by a door and those drapes as well.
What do you suggest?
My Jack Russel does the same thing and I can not break him of it. Along with curtains, furniture legs, corners of beds, Teen backpacks are his favorite! I am at my wits end and am moving to a new larger house and do not know what to do with him. I feel I may have to restrict him to one room and this makes me sad. I now diaper him in the house, which embarrasses the hell out of me, but he is quite masterful at getting it off… I know it is a dominance issue with my older border collie. Also, its always worse during and after boys and men have been over…as he shows off for them seriously bad. His in every other way is great, but this is really got my anger issues up with him.
Hi Skye,
Oh boy. Sorry to hear your Jack Russell is giving you such trouble with his marking! Is he neutered? If not, get him neutered as this will reduce or possibly eliminate the behavior.
Also, you can try getting some pheromone diffusers for the room/s he marks the most. This mimics is a natural calming hormone in dogs. If he’s more relaxed, he may mark less. I like these: https://amzn.to/34U8phz
You can also take him to a veterinary behaviorist who can help resolve the problem through behavior modification or possibly medication.
Keep me posted.

Hi Helen,
It’s not uncommon for male dogs (even neutered ones) to start marking when there are changes in their environment.
It’s possible it may subside. In the meantime I would talk to your vet about this behavior and have him examined. The vet can rule out any potential medical issue.
Also, he could be marking due to anxiety related to the changes. You can try getting him a pheromone collar — a natural way to calm dogs. I like this one: https://amzn.to/2Pmj37G
Good luck and keep me posted!

Hi I have a male standered poodle who’s 6 months fully potty trained he isn’t aloud on couch but yesterday was different I was in kitchen he got on couch and just peed then hours later I was in bathroom and came out he had doe it again HELP
Oh my! That’s not good Verna! It’s possible he has an underlying medical issue leading him to urinate inappropriately. I would ask your vet about this. If there’s no underlying medical issue, he could be marking territory he knows you often frequent. Is he neutered? If not, neutering him can really help with inappropriate elimination. I hope this helps!
I am almost scared to get a second dog do not want to deal with possibility of tripp marking inside the house (my two year old morkie) he really is house trained but when we went to visit a friend recently he did mark inside their house and they have dogs
Hi Annette,
Maybe you could try inviting a friend to bring their dog over to see if Tripp marks in the house during or after the other dog is there.
I don’t want you to be afraid to get another dog! But its definitely good to know if you have a dog that will possibly mark his territory when his “environment changes” (aka, new dog!).
Keep me posted!

We adopted a 30 lb mixed breed short haired rescue dog last summer. He is 3-4 years old. He is an active dog and we are an older retired couple. As I look back on it, we were not a good match, but the dog needed a home, so we took him in. He was supposed to be house trained, according to the foster family ( who had another dog and a fenced yard). We have a cable run and no other pets. After several accidents in our house last summer, he understood house training on his own, not dependent on another dog to go out. He went to daycare once a week run and play. Since this pandemic, the doggie daycare is open only to medical personnel and police, firefighters, paramedics, etc. so our dog has not been to daycare in almost two months. I have back issues and play only easy games like fetch with him. He used to sit in our front bow window and watch the quiet street. About two weeks ago he suddenly started marking in that front room. I found dried drips on the floor by the couch, the chair. And the draperies. I cleaned up each as I found it, but he went to another area. He goes out many times a day so it certainly isn’t that . This seems to be marking.
Yes, it sounds like he’s marking. Is he neutered? Unneutered male dogs are more likely to mark territory. If he’s already neutered there are a few things you can do. First, be sure you’re cleaning the urine with an enzymatic cleaner. Other cleaners don’t remove the odor entirely. When they can smell it, they are more likely to go again on the same spot.
His routine change (not going to daycare) could be part of the problem, so hopefully they will be able to open soon so you can get him back on a routine. The activity and socialization is good for him.
I hope this is helpful! Keep me posted.
I have a dog called prince he is one years old. He is marking on all the furniture in the house and on the floors.
please let me know how to stop it al together
Oh gosh. You must be so frustrated! Is Prince neutered? If not, I highly recommend you have him neutered. Unneutered males are more likely to urine mark their territory. They do this to let other animals know this is their territory and also to communicate their reproductive status. Also, it’s important to clean up all the urine smell, stains with an enzymatic cleaner. Eliminating those odors may prevent your dog from peeing on the same spot. A vet checkup would be a good idea to make sure there’s not a medical issue causing him to excessively mark and finally, try taking him outside more often to encourage him to mark outdoors. I hope this is helpful! Please keep me posted.
he is not neutered.but Is their any other products we can use instead of enzymatic cleaner because he keeps doing in the same place or any other products since the places we can find enzymatic cleaner is in pet stores which are close due to the pandemic. let me know thanks
Hi Serena,
There are links to some enzymatic cleaners in this article above that you can get online. The trick with enzymatic cleaners is you have to soak the area where the urine is. Soak it (but don’t flood it), scrub it just a bit, gently, then cover it with a cloth and give the enzymes 24 to work their magic.
Another thing to try is to watch Prine when they are indoors for signs that he’s thinking about urinating. When he begin to urinate, interrupt him with a loud noise and take him outside. If they urinate outside, praise them and give them a treat.
Hi Serena, If you’re using an enzymatic cleaner, there’s a trick to making sure it completely removes the stain and odor. You first soak up as much urine as you can with a paper towel, then you have to soak the spot with the enzymatic cleaner. Dont’ flood it, just apply enough liquid to “soak” the stain spot. Then, lightly rub the cleaner into stain area. This is is what activates the enzymes to work. Then, cover with a cloth (white preferably) and let it sit for 12-24 hours. When you remove the cloth, it should be gone and dry or mostly dry. You can then vacuum the spot.
Hope this helps!
Hi Kristin. I am seriously at my wits end with my male dog! I have had Milo, male, and Mia, female, since they were puppies when we adopted them from a rescue shelter. They have the same mom. They are 9 years old now. Milo has always been anxious and has always marked, but we lived in a home with wood floors and blinds not curtains. So the few places he marked we could spot clean easily. We have moved in the last 9 months! We have brand new carpet and new curtains that hang by the backyard slider where there doggy door is. On the curtains and carpet by the slider is where he loves to mark now. It just smells! I spot clean, I carpet clean. What do I do??? Help! This boy drives me crazy. I need those curtains up too or my will be an oven. Oh and yes they are both spayed and neutered.

My young pup is peeing on my clean laundry as well as my bedding, one night she even peed on the bed with me laying in it yet I wasn’t able to catch her in the act. She is neutered and doesn’t have any health issues so I honestly don’t know how to tackle this issue
Hi Lauren,
How frustrating! I’m sorry to hear you’re pup is peeing on bedding and clean clothes. Here are a few suggestions to tackle the problem.
Take her to your vet to rule out a medical problem (UTI, etc.).
Sometimes neutered dogs mark because they’re stressed too, so you might try a calming pheromone (see link below) to relax her.
Be sure to completely eliminate the odor in your bedding and clothes with an enzymatic cleaner (link below). You can use it in your laundry, which is what I do, and it works great.
Also, and this is obvious, keep a REALLY close eye on her when you think she might mark the bedding or clothes. If she signals she’s about to start the behavior, immediately take her outside, and praise/treat her when she potties outside. If you can catch her enough times before she does it, you may be able to reshape the behavior.

Hi Nicole (marking in Oregon),
I’m sorry for the delay, I somehow missed this comment on the blog.
You mention that Milo has always been anxious. Anxiety in dogs can cause them to mark territory. So, I suggest a few things.
First, I would try getting him a pheromone collar by Adaptil. Pheromones mimic the natural scent produced by a mother dog to calm her puppies. You can also get Adaptil in a room diffuser or spray form. Try those first to see if it calms him and reduces or eliminates the marking.
If that doesn’t work, I would talk to your vet about Milo’s marking to rule out any medical issues. You might also inquire about working with a veterinary behaviorist to help you modify his behavior. There are also some mild medications your vet may prescribe to calm his anxiety to stop (hopefully) the marking.
Keep me posted. I know how frustrating the problem is!

I have a neutered 2 year old havanese. He is potty trained. I can leave him on the first floor for many hours unsupervised and not have an issue. If he gets upstairs, he will mark on the corner (on the floor) or my bed or my daughters. If he gets into the basement he marks on the corner of the couch/carpet. He only has accidents in places he isn’t allowed very often. I am tired of having a gate on my stairs. He has even done it immediately after being outside. Why is he doing this?
Hi Stacy,
I’m sorry to have missed this question. This thread gets so many questions! How is your havanese doing with the marking?
You asked why he does this behavior. It could be a variety of reasons. Neutered males mark for territory, signal to the opposite sex or because they are stressed. Or, there could be an underlying medical issue.
You say he’s only marking in areas where he’s not allowed. So, he either feels the need to leave his mark behind, or those areas stress him for some reason. Or both.
After you clean the soiled area to remove the odor, try playing with him in the areas where he’s marking. This might make him feel more comfortable in that area, reducing stress and reducing his need to mark.
I’d also talk to your vet about this. If the problem persists, it might benefit you to talk to a veterinary behaviorist about how to solve, reduce or manage this annoying behavior.
I hope this helps Stacy!
I have a 5 year old female rescue dog who is fixed. We go for walks twice a day and she marks many many times on the walk. She squats or will lift a leg up on the curb to mark. We have not moved and no other pets in the house. It seems it is getting more frequent.. I am retired and do the walking with her.
Hi Jane,
Is she only marking outdoors? Or indoors too?
I have a 6 yr old neutered male Rottweiler/ American Bulldog mix. My other dog is a 2 yr old spayed female Pug. When he sees her urinate in the back yard he runs over and pees onn her back. If im outside and he knows I’m watching he will wait until shes done then run over to cover her scent with his…but if im not there he wont wait . This tells me he knows he is not to pee on her but does it anyway. How can i cure him of this ??????
Hi Ted,
He may not necessarily know you don’t want him to pee on her, he may think you just don’t want him to pee where she peed. Possibly, anyway. Can you let them out separately? I realize that may not be very convenient. Could it be that he pees on her back because he means to pee where she peed?
Very interested in your response to this as my 19month female pomchi is the same. However she will periodically Mark in the house on the spare bed if I accidentally leave door open. Brand new mattress to me so no dog there previously.
I have a 7 month old male puppy who has been neutered and we have been using an enzymatic cleaner when he does mark, but he continues to do so. I’m pretty sure its marking because it’s just small amounts in drops that spread across pillows, couch, wall trim, etc. I really have no idea what else to do! Help!
Hi Kristen,
How’s your puppy doing with the marking? I’m sorry I didn’t see your comment sooner. This thread gets so many questions!
Here are a couple of things you might try.
Clean the soiled areas super thoroughly using a cleaner specifically designed to eliminate urine odor. You may have been doing this already, but if not, make an effort to completely eliminate the odors in case he is marking in those places because he can still smell it from the last time. You’re using enzymatic cleaners which is good, but be sure to thoroughly soak the area he pees on (don’t flood it, just soak it) and let it sit for 24 hours to allow the enzymes to completely eliminate the odor/stain.
Another thing to try, make previously soiled areas unappealing or inaccessible to your dog. Put something around the area to prevent them from getting to it (like a piece of furniture or something). This can be temporary to see if he stops the behavior or he begins to mark somewhere else.
If this isn’t possible, try to change the significance of those marking areas to him. Feed, treat and play with him in the areas where he marks (after you’ve eliminated the odors).
I should also say that it would be a good idea to take him to see your vet about this specific issue to rule out a medical problem like a urinary infection or something.
I hope this helps. Keep me posted!

We have had an increase in marking over the last 2 weeks with our 2 1/2 year old neutered male that was adopted 8 months ago. When he was adopted there was 3 adults and 4 kids in the house. About 3 months ago 2 adults and 4 kids moved out and two adults moved in. There was no change in marking behavior and his overall behavior became drastically better. Now he has started to mark in the house over the last two weeks. He peed on the bottom of a recliner and on the bottom shelf of a coffee table in the last week. Recently we brought home a rug (that was borrowed for about a year by a friend who has a dog). Our dog is best friends with their dog but I am wondering if there is any lingering smell of the dog causing him to mark? But he has also pooped in the back bedroom (not where the rug is) and marked on a bag of pool supplies outside. Now I am not sure if there is a larger issue. He is outside a lot of the day with the option to come inside whenever he wants. He has an acre to roam around outside. What do we do?! We cant take away the furniture. I was going to try to shampoo the rug. I have already been spraying where he has marked with urine remover spray. HELP please!
Oh my Lindsey! Your poor kitty has endured a LOT of changes recently.There’s probably a very good chance his new marking is a result of his environment changing so much. Cats like to control their own environment and when they can’t it causes them stress. Sometimes it presents as hiding or self harm or crying – in this case, marking and making you nuts! Two things…. talk to your vet to first rule out an underlying medical condition that could be causing the behavior. Secondly, see if you can stablize his environment. Give him an opportunity to control his surroundings. For exmaple, if he has a favorite room or part of the house, keep him there and dont’ change anything or anyone going in and out. Also, I just published a guide intended to help pet owners prepare their pets for going back to work after quarantine. The advice may work for you too. You can download it here: https://www.kristenlevine.com/back-to-work and see pages 12-18 specifically about cats! Thank you for reaching out.
I have two dogs that I bought together at the same time and are the same age. I have always found problems with them trying to dominate and mark their territory. The only thing is they are both neutered and only mark selected items like blankets and beds. We could never get them real beds from a store because they would immediately mark them so I gave them old outdoor pillows and have never found a problem. However winter is coming up and they are shaking at night so I have given them a large blanket to keep them warm and they won’t stop marking them. I have tried everything even giving them seperate areas or separating them but it only ends with them barking all night until they are brought back together. I don’t know how to let them sleep together and not mark territory.
