I agree he is precious no matter what! Although he did destroy my $200 glasses yesterday. I guess I knocked them under the bed and I thought he was under there sleeping:( He is teething bad! I doubt he has rat terrier in him because he doesn't look it and he is going to be about 70 pounds, already 35 at 4 months. The foster home also gave me medical papers for him saying he's female, didn't have his vaccines up to date and were very unorganized with a lot of sick dogs. They have no clue. It's just interesting to ponder his breed when certain breeds carry particular traits.
