When we were discussing getting a puppy about 4 months after we lost our 16 year old dog, I was totally a apalled at the idea of a crate. No way would my dog be caged! Then, after reading and researching plus Bonnie was in a crate from being born, I relented. Best thing ever. For us, same as you, Bonnie was a dream to toilet train and not one thing chewed (except her own toys; she can still destroy a dog toy in less than a day
). I'm a big convert to crates, if the pup is happy in them of course, which Bonnie always was. She would still sleep in one I think if we had one up.
We let Bonnie have the freedom of the kitchen and dining room around the same age, 6 months, and she was a star. Never did chew anything so here's hoping Charlie is the same xxx
