My wife and I have enjoyed the company of two B's over the last 3 years. They are perfectly crate trained to the point where they sleep in their crates with the doors open all night.
We've recently adopted a male foster B, and we are overjoyed at the new addtion to the family (the resident male B probably isn't at that point yet, though). However, we've noticed that our new B, a 10-month old, acts quite anxious in the crate. We suspect this stems from having been stuck at a Petland store in a display crate for more than 4 months before being purchased and consecutively owned by two previous families before coming to ours.
Any good tips on deconditioning the bad experiences of crating for our new B? We've got him going into the crate and sitting for a treat, but closing the door seems to make him frantic. We've left him in there for a few nights, but his constant anxious behavior has trained us to let him sleep with us. It's gotta end so when we travel, he'll be ready to sleep in a crate at night at the dogsitter's place.
