I have an Australian Cattle Dog, as you are fully aware, are a very smart
dog and have a lot of energy. He's only two, so I believe this behavior can
be changed. My biggest problem right now is with his aggressive behavior
towards strangers that come on to the property. He will charge, bark and
nip at them. Will secrets of dog training address this behavior? If this
behavior continues, I may have to get rid of him.
