Has become aggressive
Goose is a Dobie/Mountain Cur we got from Dobie rescue 3 months ago; very sweet to us, was great around guests, kids... was pre-approved as a therapy dog, had some obedience training... He came to us with some behavioral issues (poop, pee in the house, counter surfing, a bit too playful with our other big dog though they seem to mostly enjoy the play) and while I am working his on-leash obedience training daily, last week he bit a neighbor and yesterday out of nowhere (while on leash) aggressed toward a next door neighbor. He also is aggressive toward her through the fence we share. Need to resolve this asap. My husband thinks maybe the warning/shock collar? Again, up until last week, I would have trusted him completely around guests. Need an answer I can trust! So many opinions about training out there!
