Super light, adjustable ID ONLY collar. This collar was designed after many requests for a collar to fit the "In Between" size dog. For the dog who isn't a little dog and isn't quite that medium size dog. We like to call it the "Benji" size. The Ultra Lite is designed just like our Original "Snickers" Collar except it is lighter and thinner for your dogs comfort. Don't let the sleekness confuse you.. the Ultra Lite has been tested on all sizes of dogs from Toy Yorkie's to Rottweilers. Rubber coated adjustable sliders allow you to create the perfect fit for your dog and will not tangle or mat the fur.
