^^^^^ I agree with the above user; just as dog species that are larger/have a greater propensity to bite aren't evil, and are safe to keep around young children of you have the same safety precautions, the blood should be the same.
For instance, if I ever get a dog it will probably be a pitbull. my best friend grew up with a pitbull, and it was the sweetest animal ever. His dad (the COBE in our congregation) tells stories of the dog playing with him when he was 2-3 years old, etc.
i want to raise a responsible pitbull so I can show my other friends and relatives that pitbull are not evil animals, and that they can and do make good family pets.
