Different breed of dogs are bred for different traits. Shepards are bred to herd animals, retrievers are bred to fetch, pitbulls are bred to kill. And when they do attack they are much harder to stop than a Shepard or a dobbie. Just a fact. You know nothing about me and your personal insults can’t change the facts.
Your ignorance is showing. The "nurse dog" was not bred to kill.
Is there anyway possible you could possibly do some research instead of just posting more uninformed crap wee lassie?
