Darlene, I have been asking myself the same question about my boys, lol. You may recall that they are full brothers, different litters, and Teddy was a full 8 months old before he came home with me. I have been joking ever since that I should have let our breeder raise Maximo until he was that age.
Maximo is a pretty good guy, but Teddy is a dream because the breeder trained him.
