15 week old cocker spaniel - she loves the crate and happily goes in there to eat and nap, and also at nighttime bug she does NOT like the door shut and barks and howls.
I want to start leaving her alone for very short periods of time but I want to start shutting the door. My worry is, if I start, will she then associate that with negative feelings and not want to use it at all? Really not sure what to do. She's not a chewer (yet) but who knows what's round the corner!
