I bought these on a whim because Texas Toothpicks are hard to find, I don't trust Greenies, and Gizmo hated Nylabone's Nutri-dent bones. Also, he's on Blue Buffalo food and, since he's such a picky eater, I figured might as well stick with a company that works.
Anywho, Gizmo is a avid bulley stick chewer so I knew I needed to find him something to be proactive in his dental hygiene. I must say he absolutely loves these! They stink to high heaven, but they seem to work pretty good. My only complaint is the the "Mini" size which is for dogs 5-15lbs are really tiny and Giz goes through them very quickly. Also, I usually end up throwing the little end out instead of letting him eat all of it (possible choking hazard). So next bag I get, I'm going to get the size up. So far, his poop has been normal, and they haven't upset his stomach.
4 thumbs up!! Great treat to give before bed time to get rid of any access energy!
