* Excitement urination: Some dogs, especially puppies, might experience excitement urination when they get overly excited, which could happen during playtime.
* Submissive urination: If one dog is feeling submissive to the other, they might pee as a way to show deference.
* Medical issues: There could be underlying medical issues that lead to incontinence, such as bladder infections or kidney problems.
Important Note: If you notice your dog peeing frequently or unexpectedly while playing, it's best to consult with your veterinarian to rule out any medical conditions.
