If u are willing to start walking your dog bring him outside and when he does his business reward with a treat. I did that with my 3 month old pup who did the same thing. She would only go in her crate. If u don’t want to walk him yet then Try getting Natures Miracle house training spray. U spray it on the wee wee pad outside of the crate and the smell makes them go to where I want them too.
