Benebone chew toys are made of super-strong nylon and food-grade bacon, peanuts, chicken, maple wood and jack salmon. We use no chemicals or artificial flavors. Each of our products are Made in the USA and is 100% USA source. The Medium Puppy Wishbone is for puppies under 60 lbs. and is designed with a slightly softer material makeup dedicated to teething pups. Since dogs don’t have thumbs, why give them a chew that you can pick up and they can’t? With real bacon infused all the way through, your dog’s wish is coming true.
