I don’t have too much trouble with any particular breed. More concerning is the usual lack of socialization that these dogs have. Almost invariably sold or given away in front of stores ( think Wal-Mart)at 5 weeks of age. And a lot of them, at least around here, are at least half pit. See my profile page for a picture of mine....exercised Well socialized, exercised every day, taught to hunt ducks, and still more of a handful than twins.
Wow.
That is a stunning dog.
