Petco doesn't answer questions here. However, I have an aggressive chewer and she loves their filled bones. They come in different flavors chicken, cheese and bacon, beef. You can also buy what's called a Kong it's red. Make a mixture of chicken(canned is fine) and plain yogurt put it in the Kong and freeze it. It will keep them busy for a long while.
The veterinarian is not a fan of rawhide. Apparently not terribly nutritious and if swallowed in too big a chunk can lodge in the intestine. That's not good... I give them Smart Sticks. Safer to eat and healthier. They don't last as long as rawhide though.
