Not that im biased at all , lol , but you've picked the most intelligent breed as your pet

My Toffee , somehow , managed to open his crate door the other day ... no idea how and he hasnt done it since , im wondering now if I shut it properly
anyhow , dont let him get into the habit of telling you what to do ... I think its just a case of plowing through and ignoring the yelps and whines for a few nights (make sure he doesnt need the toilet obviously , but dont hang around when hes done)
Its hard to do I know , I felt incredibly guilty hearing her whine and not going to her (plus I felt sorry for Toff , their crates are in the same room) , but after 4 days she settled at night and now, as I said, will go from 1am to 7am quite happily
One tip I got was leave one of your t-shirts with him in his bed ... it didnt make much difference with Gypsy but it may for your Charlie
