A bully stick is a dried bull's penis. You're right it's not a brand name, although there are several brand names, like Merrick's, etc. There shouldn't be ingredients listed as nothing should be added to the stick, unless it would be a preservative. I buy bully sticks from two different YT members.....AMD with Westbrook and BaxtersMommy.

I prefer to supervise my dogs anytime they have a bully stick, although I'm aware of others here that do feel comfortable leaving them while at work. I've had one of my dogs start to gag on a bully stick that had become stringy after being chewed for awhile.
