I am adopting a 3 year old english bulldog. the owner said he is toilet trained but he is kept outside of the house with a mini lawn and he does go to the lawn to settle his business. I live in a condo so I won’t be able to provide him a lawn. I wish to know how can i toilet train him with him at 3 years old? what can i do? I can’t paper train him because he’s anti paper lol. Please help.
