Okay, I got that pitbulls have poor eyesight and have difficulty in distinguishing the dog food meat from the hand holding it but there is some questions I have about the attack.
How did the dogs plan that this was the day they would all attack ?
In a Disney movie Toni the leader would call the others around and plan it. 'Little Jimmy the pup fakes an injury. Frank, when he bends over you go for the nuts. Rocco and Lorenzo, you jump on his back. Me and Giuseppe will go for the neck. Tomorrow feeding time is the day. Anyone asking questions, we blame the cat.'
Most dogs with an attachment to their owner will protect them. How much hate was seething in these dogs to think ' What a great idea - let me get a few bites in' I think these dogs were breed to hate ('respect' in some owners eyes) - possibly as guard dogs. The number of dogs, there were puppies. I'm curious.
As for the breed. I knew a young couple with children that got a pitbull. I was a little worried and would count the kids when I visited to see the dog was eating more than it should. It was odd to see because this pitbull was a mass of muscle. However it was a very friendly dog and I never saw a hint of anger in it. While kids loved the dog and the dog loved the kids, it was interesting to see adults and other dogs would panic.
I am not a dog person but my observation is that dobermans, sheppards and pitbulls can be friendly pets but their physical attributes attract sickos that like to raise them as vicious dogs. Possibly these owners think they will get respect that they couldn't achieve with their miserable personalities.
