I want to know why the dog pees on the bed even though he has been outside enough times to relieve himself. He was given to me from someone who had him in a dog crate most of the time. He knows he is supposed to go outside and seems housetrained already.
Two possibilities: Could be a medical reason such as a bladder infection. If you have eliminated that possibility, it is most likely territorial marking, just like dogs do when they lift their leg outside. Even females will mark with urine. You either have to figure out why the dogs feels the need to mark your bed ( is for example, a new person sleeping in the bed?) If you cannot change the factor that is causing the dog to mark your bed with urine, the only option is to restrict access to the bed. Keep the door to the bedroom closed unless you or someone else is in the room. The dog will probably not pee on the bed unless he is alone. If, on the other hand, you see him doing it, correcting him at that time might help.
