North West PA Or 20 yrs behind the West | I have had several breeds of farm dogs. Blue heelers can be a little bit of a biter. Neighbors heeler are pain to be around. Border collies and Australian shepherds have been the best for us. I have a three way cross of heeler, collie and Great Pyrenees. Friendly dog but he likes to visit neighbors. No more males for me. My females have been good at not visiting neighbors |
