What does the containment collar consist of?
There is a small receiver box on the containment collar that picks up a digitally encoded signal from a transmitter. Containment collars vary in size, and dogs as small as 5 pounds can wear a collar comfortably. Properly fitted, the collar should be snug, allowing enough room for one of your fingers to fit between your dog’s neck and the collar. The size and weight of the receiver normally does not cause any distraction or discomfort.
