Thank you so much for the video!!!! It personally touched me because my parents have a pit bull rescue dog named JAG, his previous owner used him as "bait" for other dogs to attack. BUT you could never tell he is the sweetest pet. They have had him for 5 years and we all love him so much. Most of his scars are gone now.
Also my parents have had pit bulls before, in fact my brother used to be carried around by his diaper by their dogs Major & muddy bottom. They are very loyal dogs!

An animals behavior is learned by their owners!!!
