San Francisco, CA
We have had the same dog walker for 2 years. Our Collie began showing signs of aggression recently toward large dogs and our walker fired us. It came as quite a shock to us. We were at a total loss because we did not know what was going on. We hired a couple of trainers to no avail. After waisting over $1500 on trainers that could not help us we found Kevin's website through S.F. Gate online. He was patient and knowledgeable but most of all he understood the problem. After putting our dog in his Behavior retreat for 5-days and following up with his free private session the problem was fixed! Highly recommended.
