If you have a collie puppy who is weeing on the bed, there are a few reasons why this might be happening:
* Puppyhood: Puppies are still learning bladder control and may have accidents.
* Not Potty Trained: The puppy may not be fully potty trained yet.
* Medical Issues: There could be underlying medical reasons like a urinary tract infection or bladder issues.
* Stress or Anxiety: Changes in the environment, new people, or other stressors can lead to accidents.
* Lack of Attention: A puppy that is not given enough attention may resort to accidents as a way to get your attention.
If your puppy is weeing on the bed, it's best to consult with a veterinarian to rule out any medical causes and get professional advice on how to address the issue.
