Review on Waterproof Remote Dog Shock Collar with Beep, Vibrate, and Shock Functions - Training Collar for Small to Large Dogs, Rechargeable with Diamante Bling by Megan Evans

I bought this collar because it is one of the only training collars for small dogs under 10 pounds. The only thing it does for small dogs is that it comes in two collar sizes. The device is the same size as for large dogs. Once the collar is adjusted to the size of the Yorkie, it is very difficult to get to the charging port on the device as the collar is adjusted to the smallest size and fits snugly against the device and the charging port is underneath the collar. I only use vibration and a beep and that's enough to keep my dog's unwanted aggressive behavior at bay. Since I don't use electroshocks, I adjusted the collar and attached it to the seat belts. This method works fairly well and doesn't have two teeth on the neck. It would be nice to see a device with a smaller remote control for dogs under 10 pounds.
