Advanced simplicity is what we strived for with the Dogtra 280C e-collar, offering all the key essentials for dog training in an ultra-compact unit without sacrificing the benefits of a remote training tool. This is the perfect remote training tool for basic obedience or field training where you need a reduced size receiver/collar for a smaller dog. It is designed for dogs as small as 10 pounds. The 280C e-collar is packaged with the smallest ultra-compact receiver from Dogtra that offers low-mid stimulation from 0-127 levels at your fingertips. The 0-127 stimulation level is controlled by a Rheostat Dial, a patented technology from Dogtra to ensure a precise setting for every dog. The 280C is also available in the 2-dog system, 282C, to train two dogs at once.
