There are no bad dogs...just bad owners. If your child bites someone or steals something...should we put him or her down? Should we say that the kid is just a bad breed? No...it is improper upbringing, lack of parent guidence. Same with animals. If they are treated correctly and not put out in the yard to just sit in the elements with no attention, then yes...they can become aggressive. Heck...I have seen toy breeds bite people. Use education people and guidence with your children. For example, all these women who take their children to school every morning...you drive like idiots and disrespect others on the roads...do you not think your kids are picking up on this? If you cannot raise your dogs and kids properly...don't breed em, don't take em in.
