Mission accomplished!  We started with our beagle who is 9 years old and prone to nipping at strange men and going bonkers when we go on walks and encounter other dogs.  After working with Bob, we had a calmer, gentler dog who is a pleasure to take on walks now and we no longer fear having new people visit.  What I liked best was seeing the transformation almost immediately and having a dog run up to us with no leash on and my beagle not react or engage at all with the dog.  Bob really knows his stuff!  I'll be recommending him to anyone who needs dog training!
