dogscrimination
When your dog is treated unfairly by your wife/girl friend in favor of her dog, usually a lap animal that more favors a cat than a dog. The unfair treatment usually involves what food/treats they get, where they are allowed to sleep, and how much time you spend with them.
When my wife allows her poodle to sleep on her pillow and makes my dog sleep on the floor, it is a clear case of dogscrimination.
