Dog marking is when dogs leave small amounts of urine on furniture, trees, or bushes. It’s a way for dogs to mark things as theirs. It leaves behind a scent that other dogs will smell and know that tree or couch has been claimed by that dog.
This may also be known as urine marking or territorial marking. Territorial marking is also very different from dogs having accidents in your home. Dog marking usually begins at the adolescent age, typically after your dog has been potty-trained. While dogs do mark to claim things as theirs, it can also be a sign of anxiety in your dog.
