But believe me some dogs ARE born more agressive than others, especially when it comes to bull and terrier breeds and dog agression. Some pups run hot to use the term and will have to be seperated from the rest of the litter for the siblings safety.

I dont see too much wrong with having a DA dog, it is just correct management that ensures it will not be a problem within the community.
