Every time I give my 3 month old bulldog a blanket to lay on he pees on it. Its as if he is marking his territory. How can I stop him from doing this?

Don't give him blankets. Let him find his own corner to sleep in on his own.

Tick

Well he will pee on anything we give him to sleep on. So should I just let him sleep on nothing in the crate?

Quit giving him blankets

Where did you get him from?

This is bedding in his crate?

How long is he left in his crate?
Does he pee when he enters the crate or after he has been left for awhile?

How is he doing on house-breaking?
