Review on 🐶 PetSafe Remote Training Collar - Tone, Vibration, or 15 Levels of Stimulation - Suitable for 1 or 2 Small, Medium, or Large Dogs - 100 to 900 Yard Ranges (300-2700 FT) - Waterproof, Durable, Rechargeable by Paul Curd

I bought this for my 6 lb dog who is too small for most behavior collars. This collar can be adjusted to fit the neck. The block itself fits well and isn't too big for him, although proportionately too heavy to fit around my dog's neck. Before using it for the first time, I tested it on my hand and I felt it for the first time. on level 2 i feel a bit uncomfortable on level 3 so i only use it up to level 3 on it. I'm guessing that he has a strong mood for level 0 because it often gets his attention without getting tens. We've gotten to the point where when I put a collar on him, he doesn't act up, but he also wags his tail. in excitement. He seems to associate the collar with a good boy, so he appears calmer and thereby draws more attention to himself. Overall this is a really great investment for teaching my stubborn boy.
