Why does my house-trained dog mark when an unneutered dog visits?

He probably started marking when his hormones increased. Now that he’s neutered these levels will go down over the next four to six weeks. Please clean all of the area he’s marked with lemon or vinegar cleaner to remove the scent. I recommend going back to crate training for housebreaking, or using a male belly band when you aren’t able to monitor him. Please take him outside or to the pee pad frequently so he has a chance to urinate there. Marking behavior can become a habit so working to stop this right away is best.

Unneutered male dogs have the highest likelihood of “marking” around the house. However, some male neutered dogs and an occasional female dog will also. Any new dog you bring into the house should be confined to small, safe areas unless supervised for a while until you know their marking/ urination/ defecation/ destruction habits. Best of luck and I hope you enjoy your new dog if you get one! Thank you for using Pet Coach.

Inappropriate urination occurs when a dog regresses to urinating inside the house. This behavior is more common in male dogs that have not been neutered, although it can occur in non-neutered dogs and cats. The first thing to rule out is inappropriate urination that occurs when there is an underlying health problem which is causing a dog to urinate inside the house. It may have lost control of the muscles in its bladder or sphincter, or there may be an infection (UTI) or other condition as drinking too much (seen in many medical conditions) that is making it difficult for the dog to hold it in long enough to get outside. When a medical caused has been ruled out we can think about the second type of inappropriate urination which is behavioral (such as marking). I recommend to take Bakar to the vet with a "fresh" urine sample to first check or rule out medical causes. Hope this helps and thank you for using Petco Pet Education Center, formerly Petcoach.

Thank you for submitting your question regarding Cashew. I recommend having him neutered. He is coming into puberty which is why he had started the urine marking behavior. Neutering him will help to resolve this behavior. It will take about 30 days after the surgery for the testosterone to leave his system. It may not resolve the problem entirely as it can become a learned behavior, but it should decrease it significantly. I hope this information helps!

The short answer is: maybe. Urine marking can develop into a set habit of behavior, and it can be difficult to get them to stop completely if they weren't neutered at an early age. However, in trying to minimize the behavior, the very first thing you should do IS to neuter your dog, so you're already on the right track. Here are a couple of great articles that you may find helpful in terms of curbing this behavior. https://www.spca.org/document.doc?id=116 https://www.petcoach.co/article/7-rules-for-effective-housetraining/ I hope that helps you!

This can be either a dominance issue, or a submissive behavior, as he is still a young dog. You can use gentle correction at the first sign he may try to mark, but it is not an indication of anything serious. All dogs perceive their world just a bit differently from one another. Just like people. Work with him to discourage the behavior & try not to put him in the position where he needs to mark other dogs. He will hopefully outgrow the behavior.

This can be a frustrating problem in intact males! The first thing I would do right away is have Junior neutered - many times, this will decrease the marking behavior dramatically even if it's already been going on for several years. After this is done, you will likely still need to work with him a bit on housetraining. Treat him like a young puppy who has no idea where to potty - take him out frequently, praise and reward for peeing outside, and supervise constantly indoors to prevent accidents. If you see him starting to lift his leg, clap your hands and say "ah-ah!" or "no!" - he will soon learn that this is not acceptable in the house, if you are consistent. Don't relax your supervision until he has had at least two weeks with no accidents at all, then increase his freedom in the house very slowly. This will take time and patience, but it can definitely be done.
