Too expensive!

These are the best pig ears for my dogs but they are too expensive. Bring the price down. After all they are just pig ears. ☺️

Will definitely get more for my pig ear loving boy!
Flavor Name: Pig Ear, Size: 8 Count (Pack of 1)
My shar pei mix baby LOVES these! He is about 4 months old, teething and always has food on the brain. These do the trick! One ear lasts him about 2 days if he is really going at it, sometimes longer. He will work on it for hours at a time. They have little to no smell. He chews them on his white dog bed and they leave no stains or marks. I love that there aren't any extra ingredients so I know exactly what he is ingesting. I will DEFINITELY be buying more of these!

Is Milo allergic to pig ears?
Flavor Name: Pig Ear, Size: 10 Count (Pack of 1)
Milo sniffed the pig ear, paused, and then took it to his spot to eat it. A few minutes later he started rubbing his head on the floor. I also bought the cow ears and he ate them with no problem. I’ve snuck him the occasional piece of bacon so I don’t think he’s allergic to pork. I love and trust Nature Gnaws.
