I truly believe that some dogs are inherently unstable dogs who cannot be helped... just like some people, some animals of any species, can never be "normal".
I agree with that totally. In the way humans are mentally challenged i feel dogs can be like that too. wiring gone wrong during fetal development. working at a grooming shop i have had thousands of dogs in front of me and have noticed just odd behaviour(like one puppy i groomed at 3 months was very aggresive and i dont mean biting out of fear it was full blown aggresion and it was a shih tzu pup). I have asked a few vet friends and they all agree there are mentally challenges dogs. while in school i worked with mentally disable kids and there wer ones that were just very slow and there were some that got very aggresive when they were challenged, again i belive that dogs are the same way. and when the wiring has gone wrong there is nothing you can do to fix it. not even cesar, though i do love his ways.

I cant remember where i had read this but its a tested thing in dogs that pits are one of the most well rounded if you might say dogs there are. they great with kids, other dogs(if socialized properly, same as any other dog), less likely to snap at nothing, they usually have a good reason, very trainable, great couch potatoes when you want them to be and athletic both at the same time. there is a whole buch of reasons why they ranked the top of the list of dogs tested but i cant remember the site i found it on.
