We pick up our chocolate lab pup in a few weeks time so we are looking for as much advice as possible on crate training. When I had dogs as a child there was no such thing so it's all new to me! Also, we are looking at a 'large' crate that measures 107 x 72 x 79, do you think this is big enough for a lab? I have LOTS of questions before he arrives so I may be bugging you all some more!
