I called K-9 Solutions because my dog Sheriff, who had been abused before I bought him, was aggressive and had bitten several people. Carlos helped me understand how to work with Sheriff to better control his behavior. He was extremely kind and loving with the dog, and very patient and tolerant with me as I learned what sometimes seemed to be very complicated movements and commands for obedience training. The end result is that I am much more confident in handling Sheriff and Sheriff is learning to respond to obedience commands. Carlos also helped me work with some adverse behaviors using desensitization. These techniques have worked very well. At the end of several months of training Sheriff is significantly calmer, easier to handle and much more obedient. I am also much calmer and much.
