This is a 12" beef esophagus (gullet) that has been stuffed with a ground beef filling, with a stretched beef bladder wrapped around. It looks kind of like a bully stick but it's a lighter chew.

Any treat made out of beef gullet or beef bladder tends to be extremely palatable for dogs, so it's a great recommendation for those picky dogs. While not as durable as some other chews, your dog is guaranteed to enjoy this treat. This chew has a much lighter texture compared to a bully stick, so it's good for senior dogs or dogs who are missing a lot of teeth.
