Reddit reviews Esky Dog Training Collar Waterproof 330 Yard LCD Backlight Remote Control Dog Training Shock Collar

I had a similar problem except the cats in my situation were my other dog, a small, senior toy poodle who didn't like my dobie puppy since the minute I brought him home. The dobie would constantly try to play with the other dog and wasn't picking up any of the clear signals the other dog was sending that he did NOT want to play. It started to get really bad because my older dog is pretty vocal, so there would be constant growling and barking all day long. I bought a vibration/shock collar because a guy at the dog park told me about the great results he got from his and WOW! I never have to use the shock setting at all, I only use the vibrate feature and based on reviews I've read online, many dogs are the same. Anytime the pup got too rough with the older dog, I'd give him a buzz. He learned QUICK, and it only took about a day or two for him to leave the other dog alone. It's like he's a completely different dog now. I'd try that - anytime he starts to chase the cats or show negative attention to them, just give him a buzz. You'll be surprised how effective it is. I know that this isn't 100% positive reinforcement training because it does involve "punishment," but it yields fast results and doesn't hurt the dog in any way. Since getting the collar, my dog has perfect recall, walks on the leash like a champ and is just overall a much better behaved dog. I would sing the praises of this thing of a mountain top if I could! This is the specific model I have and it works great!
