THESE ARE AWESOME!! Though I need to cut these pig ears with an industrial pair of sheers (cutting scissors), my three 6 lb Chihuahuas LOVE these treats. It also keeps them busy chewing so daddy can get some work done. They are most importantly great for cleaning my dogs tiny Chihuahua teeth. 😁😉. These are a MUST BUY for anyone seeking a healthy, affordable, teeth-cleaning option for any size dog.

Dogs enjoy them

Pattern Name: Half Ears (15-pack)

The brand I usually get them was not available at this time from Amazon and my other retailer only had large white cow ears, which don't look appealing to me even though my schnoodle is in the with knawing on them , the sound of him taking them apart in bed in the middle of the night is something to wake up to. So I was glad to have this recommended as a substitute, and they look like they are flavor to them,the are on assorted sizes and the dogs seem to like them and in the long run that's all that matters
