If your new housebroken puppy or rescued dog occasionally pees on the floor for no fathomable reason, then you might have a dog with submissive/excitement urination issues.. If the dog does pee when you arrive home, when you're in a dominant position, or when it is in trouble, then it's probably a submissive issue.
My 7 month old lab keeps peeing in his crate overnight. We keep him in his crate while we are at work during the day, and come home to a clean crate every .
Excitement Urination. During times of high excitement, such as when you return home or company arrives at your door, your puppy may dribble or squirt small amounts of urine. This behavior is more likely to occur in younger dogs, many of which outgrow the behavior.
