They say that sometimes the over-breeding of an animal can cause this because there wiring inside there brain isn't right. Sometimes they attack instinctively, someone is mistreating them or a lot of the times they are pestered by a child for a long period of time and just have enough. Some people think when a animal is breed to be mean then the litters there after will have that in them too. Don't forget nature creates all living things but nature is not perfect. You take two sets of genes, in what ever animal you want to pick and put them together and inherently they can have abnormalities. I had a dog for almost 10 years that we found in a mall parking lot. We treated that dog better than most people live. We never abused him and his was like our baby. Then one night after my husband took him for a walk and was petting him good night he lunged out and bit my husband in the face that required 184 stitches on his right cheek, 1/2 in 1/2 out. We still to this day cannot explain why, Sampson, did it. So I know first hand that it just could be something inside the dog. We didn't know anything about his background because we found him but he never showed aggressive tendencies before this. Sad but true we put him to sleep after we quarantined him, our state law, to see if he had rabies. We were hoping he did so we could figure out why the dog we loved like a child turned. He didn't have rabies but we didn't want this to happen again, and god forbid to a child, there would have been nothing left of a child's face with this bite. We just have to respect the animal world and be cautious. Don't ever let a child put their face in a dogs face, don't ever let a child be left alone with an animal, and by all means never mistreat a animal. To this day we miss our dog but know that we did the right thing. I say Prevention is the best preventative.
