I can deal with a lot from a hound but I do not like a house killer or a chain fighter. I had this one dog who was very very well bred. He would kill a dog house with no problem. So to stop him I got some stuff from the feed store made for horses to spray on his house and I would spray it once a week. But this same dog would bark all the time, fight his chain and if he had a bone or food in his crate you could forget getting him out until he was ready or he would try and eat your arse up. I can't have that with my kids around so I had to see if he was worth the trouble. He turned out to be a screaming CUR.
