I have recently adopted a young (2yrs) pit bull mix and she is such a great dog! We go for walks twice a day, and they are enjoyable most of the time. Its when she sees a squirrel and she goes bizerk! Pulling, whining, barking......what should I be doing here? I've been pulling her along until she stops pulling, but Im pretty sure there is something different I can do. We have started obediance classes, but havent learned that yet. Any ideas?
