You are mis informed my friend dogs are gentle the reason they bite is they feel threaten or their pack aka family is being threaten I have yet to come across a dog that bites just for the hell of it they are big working dogs and if you leave them in the house all day they do tend to tear shit up but only because they have to burn off energy. I do have a lab/pit mix and she is pretty funny around new people but as you give her time toadjust to your presence she wil learn to trust she has not biten anyone who didnt deserve it and by that she chased and tackled a man trying to enter my house i came home to find him in a tree in my backyard //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gifRots are also vicious blood hungry creatures good for nothing but biting humans.
