Super light, adjustable ID only collar. The Ultra Lite was designed because dog owners wanted it, we could and it works. The Ultra Lite is designed just like our original "Snickers" collar except it is lighter and thinner for your dogs comfort. Do not let the sleekness confuse you. The Ultra Lite has been tested on all sizes of dogs from toy Yorkie's to Rottweilers and Working Cow Dogs. The Ultra Lite is perfect for dogs who use harness's, kennel leads and easy pull leads. FYI.. this collar is not chew proof but it is Handmade in the USA.
