Brick house growled at me once..and that was when I picked her up from you. Other than that she continued to growl at children and my friends that came over. I've never treated her bad not once. She was the only dog I was worried enough to take to the vet several times. That proved a lot as much as I hate going there. After I brought her back to you, several days later, you thanked me for taking good care of her.
As for the collie/coondog subject, thanks for explaining the difference between tractability and intelligence. But all I am asking for is the dogs to know-stay, come, and be quiet. That's all! If he's not smart enough to do that then I say he is not intelligent enough to learn those commands, or he don't give a shit.
