Dog aggression is NOT a breed trait on pits. They are terriers just like our Uorkies, they have a strong chase prey drive. Pits like our Uorkies also have the general terrier trait of pack defensiveness...it is this that is often confused with dog agression because they are more likely to attack a smaller dog via prey drive or in being territorial over their home or person. With the exception of the white or blue noses they have been too inbred and have a chromosonal defect that causes many neurological issues agression being one of them.
Personally I prefer Victoria but Cesar is a pretty decent trainer with a behaviorists mentality IMHO |
