Review on GoodBoy Small Size Remote Dog Collar - Beep, Vibration, and Shock Modes – Effective Pet Behavior Training Tool - Waterproof & 1000 Feet Range - Suitable for Dogs Over 10 lbs - Small, Medium or Large Size by Andrew Smith

This collar is AMAZING! I don't even need the shock function. The vibration is enough to work with my 14 lb Chihuahua mix! We got to the point where we were thinking about bringing her home. As much as I hated the thought, we were on the verge of collapse. The children were afraid of her (she growled and tried to bite her), our cat constantly tormented her, constantly barked. With this collar she is like a new dog. She is sweet and kind to children. You and the cat can coexist and be in the same room and she will not chase you. It also stops them from barking now. All I have to do is show her the remote and tell her "don't bark" and she'll stop right away. My only minor complaint is that I wish you could program it to work automatically. You have to press the button for it to work. The remote control is slim and small, so you can easily take it with you. I definitely recommend this product! It was worth the money! That's great! If you have a dog with behavioral problems, then you need this collar! You will not regret it!
