I've been using the Elk antlers & Miya loves 'em. They're a bit pricey from the local pet store but they outlast any Nyla bone by a huge margin. Miya is a pit mix & boy can she chew. The antler is one tough, all natural chew that dogs just love. If you haven't tried them yet I suggest you do. I'll have to check on line for them for future purchases.
