I had 3 trainers and a dog psychologist attempt to turn my "demon dog" into an "angel dog" with no success. Her name is Lucy and I couldn't take her outside without having to muzzle her. She would growl at me and anyone who came near her. She attempted to bite me several times. I was at my wit's end. At the suggestion of an acquaintance I brought her to Dave Cugno. Within a few months she became a completely different dog. If he can turn my dog into an "angel" he can train any dog. It's been a year since Dave trained Lucy (and me) and it's been a pleasure. Lucy listens to commands, walks nicely on a leash, and welcomes visitors to my house. Dave Cugno's Canine Center is the BEST!!!!!
