A dog is an instinctively aggressive creature. In the wild, aggression came in very handy: dogs needed aggression to hunt, to defend themselves from other creatures, and to defend resources such as food, a place to sleep, and a mate. Selective breeding over the centuries has minimized and refined this trait significantly, but there’s just no getting around it: dogs are physically capable of inflicting serious harm (just look at those teeth!) because that’s how they’ve survived and evolved.

yes of course they're predators, but as pack animals they have also evolved to communicate and co-operate with each other and with their human pack. They will use aggression when they feel it necessary, but this doesn't mean they are instictively aggressive any more than a lot of other species, which will also attack in self-defence. To survive in the wild, they need to be part of a group and the are at least as instictively co-operative as aggressive. Sure their teeth can do a lot of damage, but these evolved to eat with, any damage they can do is coincidental.

Our domestic dogs have come a long long way since their ancestors... our domestic dogs, provided they have been responsibly bred with temperament as a priority and proper socialisation is given will live happily.
