I have a six month old english bulldog who is basically crate trained and loves his crate. The problem that I am having is, everytime I put a bed, pad, towel or blanket in his crate for him to sleep on, as soon as I put it in the crate he urinates on it and then looks at me like "okay you can take it out now." He even does this as soon as he has been outside to use the restroom. I am getting more worried now because he now weighs 51 lbs. and with him sleeping on the crate floor he is rubbing his chest raw and walks with a limp when hes been sleeping for a while. Any ideas of how to correct this so he can be more comfortable would be greatly appreciated.
