This weekend in Long Island I am working with lots of different dogs and people, one of the dogs in particular is highly dog reactive and a big bite risk. So the first thing we did was stop the dog from lunging at other dogs and had the dog just hang out with a bunch of dogs, then we got the dog to make a better choice in situations where the dog wanted to lunge. Why do dogs lunge? usually to move things away from them, people or dogs, and it works.
