We started going to Sit Means Sit 2.5 years ago. My two year old Cattle Dog/German Sheppard mix had dominance issues and was extremely protective. He had leash aggression so whenever he was on the leash he would lunge and growl at other people and dogs. We tried several different training methods, but nothing was working. I heard about Sit Means Sit through my vet and once I had the demo at my house with the trainers dog I was sold. The entire staff are so knowledgeable about dogs and are really strict on how they should act, which I really like. We have been going to group classes on and off for 2.5 years. This year a new issue arose so we went back to training and it just took a few classes and working with him with the collar at home to get him right back where we wanted him. You don’t realize how untrained your dog is until you finally have complete control over them in any situation. If you are considering doing any training at all with your dog, wait until you can do it with Sit Means Sit it will be 100% worth it.
