What our clients say after training.
Real feedback from dog owners who worked with Cosmo K9 and saw meaningful progress in their dogs and everyday life.
“I own a 4-year-old Belgian Malinois who became very dog-reactive after being attacked two years ago. Taking him on runs, walks, or trips became extremely stressful because he would react to any dog in sight... During his training, my dog learned that other dogs aren’t a threat. He came home significantly more confident and less stressed in public.”
“Before training, my dog was controlling our household. She was very strong-willed, difficult to walk, and had developed aggression toward our other dog... After working with Chris, the transformation has been nothing short of amazing. My dog is now calm, obedient, and a pleasure to be around.”
“We boarded our 7-month-old English Lab with CosmoK9 for 2 weeks, and it was a game-changer! Our lab was out of control, pulling us on walks, jumping on people and dogs, and biting when ignored. Chris worked with him on self-control and obedience, and now we can take him places without too much worry.”
