These sport collars are made of Biothane and have a lifetime warranty.  Biothane is great for all sports, it’s waterproof, stink proof and heavy duty.  Great for dogs who do dock diving, when your dog is out of the pool, it dries immediately.  No more yeasty build up from wearing a wet collar too long.  Our biothane sport collars are available in over 26 colors. Keep your dog in “their” color or get a few to rotate with the seasons.  We can also engrave directly into the dog collar.  Add your dog’s name, your phone number or whatever you want!
