Canine Behavior/Dog intentionally urinating in bed after being nuetered


Hello, I have a pit bull that is nineteen months old. We just had him nuetered about three weeks ago.
He sleeps in our bed with us at night. Every time we walk out of the room, he urinates on the bed.
Now, he just urinated on my girlfriends daughters bed in the next room. He did not start this behavior until after we had him nuetered. I thought neutering was suppose decrease marking of territory, if this is what it is.
Why is he doing it and how do we get him to stop. Please help.

Thank you for your question. I'm going to need some more information in order to provide some thoughts and suggestions for you. Please reply to this response, answering each of the questions below.

Is he emptying his bladder? Or is he just leaving a little bit, like dribbling? Have you spoken with the vet yet? A new and sudden change in potty habits, especially shortly after a medical procedure in that area, should be brought to their attention. There may have been some damage or irritation to some local nerves.

Is he still going potty in the right place throughout the day? Asking to go out, or taking himself out if he has ready access? Is this only happening at night? Or is he having potty accidents during the day as well? Is it only on the beds or has he had accidents in other locations?

Was he kept overnight at the vet's for his surgery? Has he been particularly clingy since the surgery?

Was he sleeping with your girlfriend's daughter this time, or did he just wander into her room, get up on her bed and pee?

While it can take a few weeks for the testosterone levels to diminish after neutering, the process of neutering doesn't induce hormone-based behaviors. If he wasn't marking before the procedure, it wouldn't suddenly manifest after. There is something else going on.

Please speak to your vet, make sure there's nothing physical going on, and then reply to me. Let me know what your vet said, and if it's not physical, answer the above questions and we'll go from there.

I look forward to your prompt reply.

IF YOU BELIEVE YOUR DOG IS ILL OR INJURED, PLEASE CONTACT YOUR LOCAL VETERINARIAN IMMEDIATELY. THIS IS NOT THE FORUM TO ADDRESS URGENT MEDICAL ISSUES. I AM NOT A LICENSED VET AND HAVE NO DIAGNOSTIC SKILLS. ***I have been answering questions on All Experts for over 8 years now. I enjoy being able to offer assistance in this forum. I do need to be clear, though. If you’re looking for free advice about a specific behavior question, you MUST submit your question to me via All Experts. If you bypass All Experts and write to me directly through my website, I will ask you to submit via All Experts. On the flip side, if you’re local to Los Angeles and you wish to speak to me privately about an in person consultation, please go through my website. I appreciate your assistance in keeping my volunteer work on the volunteer site.*** I can answer questions about the following canine behavior issues: obedience, timid/fearful & fear-based aggression, nuisance behaviors, families that are expanding with either new human or new animal members and many other issues. If you have potty training questions please first read my trio of blogs at If you still have questions after reading the blogs you can post your specific questions here. PLEASE be as specific as possible when asking a question. Give me a detailed example of the situation - dog's behavior, body language, circumstances surrounding the issue, what the consequences are (another dog's response, your response), etc. I can only provide insight if I can get a picture of the whole scenario. If I ask for further details, please provide them. In person I would normally observe for at least 90 minutes to assess the situation and the dynamics before offering tools and suggestions to modify it. In writing it is ever so much more difficult. Thank you for your participation in the process.
