Urinating by submission or excitement
This situation occurs most often in younger(less than one year old), in a context where the dog is very excited, or feels challenged. More precisely, the problem will surface when family members meet, or when a visitor shows up at the door; it can happen when someone bends down to pet the dog or to greet him, or when the dog is verbally or physically punished. If the dog urinates by submission, you will be able to detect positions of submission such as: the dog rolls over on his back, pulls his ears backward, places his tail between his legs. If the dog urinates because he is excited, the dog is over-agitated, and will behave like a dog that suffers from submissive behavior (consult the section "Urinating by submission or excitement').
The dog develops an inability to eliminate on a particular surface
It can happen that this problem stems from an inadequate education on cleanliness. The dog develops preferences as to the place, and the type of surface he will privilege to eliminate. If the dog is deprived from going outside, he will be forced to adopt places situated mostly inside. With time, the dog will consider places outside as places inappropriate for elimination. For example, a dog that has always defecated on the grass, and must now do it on a concrete surface, will find himself unable to execute himself. Possibly, climactic conditions will prevent the dog from eliminating. At that moment, the dog will hesitate to go outside, and will prefer waiting to be back inside to find a favorite spot to do his business. Experience will allow you to tell the difference between a dog that discriminates between surfaces, and the dog that is afraid. After a while, the dog develops his own behavior patterns. Then, if you bring him on the grass, chances are that he will prefer the sidewalk! In another situation, the dog adopts his cage to eliminate (because he learned the behavior while pensioning in a pet shop); he will have to undergo behavior modification, and should not be given access to any of his favorite spots until he has demonstrated that he can eliminate on many different surfaces.
