Yeah, I think sometimes animals are just animals. Not every animal that acts out can be blamed on a problem with their owner. Sometimes instinct takes over and they do things they shouldn't do.

Yes. 

I always laugh at these arguments. Both sides can be ridiculous. I am a certified dog trainer, and have worked with many veteran trainers. It has been found, through studies and experience that some dogs, not matter HOW well you train them and how well they are treated, cannot be trained. They have underlying behavioral issues ingrained in them, mostly due to breeding. It's more likely a dog breed that is OVERBRED, have these issues. Some issues come out through behavior, some through physical health problems. 

Some Pit Bulls can be some of the sweetest dogs in the world. Others can be some of the most violent. It depends on a lot of factors, not just how they are raised and their environment or simply their breed. It also has to do with their genes and overbreeding. I love pits, and I think they are unfairly treated by people and the media. But to say that it's only one thing (environment or breed) is nothing but perception and generally only based on people's own experiences.
