Not for aggressive chewers
Flavor Name: Bacon, Size: Large - 2 Pack, Flavor Name: Bacon, Size: Large - 2 Pack
Three stars because my dogs love them. But in terms of “Indestructibility,” that’s completely inaccurate. One day in and the dogs have destroyed them, leaving jagged edges. The nylon pieces are coming out in their poop. These are definitely not for aggressive chewers. Probably best for a small dog with no teeth.

Stick replacement - But much more fun!
Size: For Large & Medium dogs, Color: beige, Size: For Large & Medium dogs, Color: beige
The Pet Qwerks Infused Nylon antler is a great replacement for a stick! My dog Rex loves to pick up sticks around the city and chew them to pieces and eat part of the bark, yet is just as excited about the infused Antler flying across the lawn to chew on. This Antler definitely has a strong scent when you take it out of the package, but for a picky dog like Rex, it is great to get his attention! We have several BarkBone products and my 80 pound dog has yet to chew through one! They are strong and reliable products. We love that Pet Qwerks products are made in America!
