Water buffalo horns make a great chew treat! Our pack LOVES them and will sit and chew on them for hours, taking turns of course, LOL. These are wonderful for your strong chewers!! These will LAST! Durable chew, but also breaks down safely vs a rawhide product. Please, never give your dog rawhide! These are great for medium to large and extra large dogs. Best for dogs over 30lbs.
