I am looking for a dog dental chew that has been removed from the shelves at my local Cub Foods stores.?

It comes in a white plastic canister type container with a green screw on top. The treats themselves are green in color with a very strong spearmint flavor and about an inch long. The canister had a sticker on the front, I am pretty sure there was a picture of a male veterinarian with dark hair on the front. The problem I am having is I cannot find them anywhere, mostly because I can't remember their name. My three local Cub Foods Managers have all told me they remember the product, but not the name. They are the ONLY things that work for my aging Chihuahua who is losing his teeth to age. PLEASE help me find their name first, and then where they may carry them. I am located in Minnesota. Thanks so much!
