Aggressive Shih Tzu
by worried gal
My dog is 2 years old currently, and though he nipped when he was a puppy, his aggression started showing after he turned a year old. He barks constantly out the window, at anyone on the street, and while on walks, he has started pulling or leaping if there are joggers or children nearby. He had also once escaped the house into our yard, where neighbour's children ran in+ he proceeded to bite one of them. It's gotten to the point where visitors are afraid to come by, as he will bark or growl (unless it is someone he knows and likes), and he will have to be kept on leash. However, if someone shows up unannounced, we struggle to even put the leash on him as he'll be too excited and will bite us if we attempt to reign him in.
We have tried clicker training-- he follows all orders otherwise, until his aggression kicks in. We have tried e-collars as well. So at this point, we are at a loss of things to do!
