Ohhhhh dear! lol! Now...you can move forward! I have heard of people using crates or boxes to take up space in the crate. Personally..I think an entirely new crate is needed. You need to start from scratch and Tubby will be confused. But..we now know why! He will catch on..back to basics and treat him like a brand new pup! If you don't, you will have a very bad big Bully!
