Well, Gunner is in the process of outgrowing his medium size travel crate. I have a new wire crate (large) with the divider which I haven't opened yet. I am just wondering if I should get him the x-large one or if I should get him a large travel crate. I like the idea of the wire crate being more open, but I am wondering if that one is big enough and for how long!?! What does everyone else prefer? This is my first experience with crates, so any advice would be appreciated!
