You can say about any dog, “But it’s trained – it’s a nice dog!”
Most of the time there is something on the news about a dog attacking its owner or any other person, everyone says “But it was such a nice dog! I never would have thought it would attack anyone!” Then, of course, the animal psychologists get involved – they try to figure out why the dog attacked. Maybe it felt its owner was being threatened. Maybe it felt threatened itself.
The fact is, all these so-called “safe” dogs are just as capable of hurting someone.
