Due to natural variations in this product, you may receive pieces that are skinnier or a different shade of color than you're used to. Curly bully sticks are made by cutting a pizzle lengthwise into strips, which is curled into a spring shape and then baked. A long lasting chew for puppies and small dogs. Recommended for small to medium-sized dogs under 30lbs and is appropriate for all life stages. This is NOT an odor free bully stick. There is some noticeable odor especially while being chewed. Dogs who are finicky eaters tend to be attracted to stronger smelling foods, so the low odor bully sticks may be a good recommendation for these types of dogs. These spiral shaped chews provide an interesting texture for dogs to gnaw on. Since it's not a straight stick, it'll be more difficult for dogs who are enthusiastic gulpers to swallow it whole.
