Bully Sticks safe to eat?

I have a 4-pound, 8-month old "morkie" (maltese/yorkie mix) who loves to chew through stuff. I was looking for chews to buy her since I don't trust rawhide, and the best I could find is something called "bully sticks". These seemed to be really expensive, but I found a site that sells them for a good price - BestBullySticks.com. It seems to be a legit site.

I was wondering if these bully sticks would work for her? They seem healthy, and a good chew for the dog who likes to eat the things she chews on.

Anyone ever get these "bully sticks" before? How are they?
