Hi friends, my next door neighbors have a 100lb rescue, healthy, strong, solid, short haired type breed. He is very difficult on leash, pulls and goes wild when he sees another dog near, while on leash. My friends have been working with him and have made great progress, but are looking for a trainer/classes, geared to strong high energy dogs. He came with baggage, and they all just need some help and teaching. Money is a factor, but I wonder who you would recommend to help them out? thanks so much!
