We are going to be crate training our puppy and I had a few questions on how you guys set up your crates. The dog at first, until he is house trained, will be sleeping in his crate and also be in there during the day while we are at work. What do you guys suggest I put in his crate? How do you guys set up your crates? We will have a wire crate which i will have to buy a sectioner to block off some of it as it is a big crate. Thanks in advance!
