maybe she's scared of the crate…my puppy kept messing in his crate for the first week i had him even when he had gone out to potty right before...it took a few days and i just tried to make him comfy in it and put treats in it for him w/o locking it, then only locking it for a few minutes at a time...now he doesn't mind it
i feel ya on the kids toys getting chewed up...i have a 1 year old girl and a 3 year old boy....i just keep telling my son if he doesn't pick up his toys now then the dog will chew them up and i kind of like it because since we got our puppy everyone has finally been putting their stuff up where it belongs
