Definitely not worth the money you pay.
Size: 14 Ounce (Pack of 1), Set name: Standard
The dogs love them and they are great treats. The problem is for almost $20 a bag. You only get a fourth of the bag hole sweet potato strips. The rest of it is just the scraps from the skin. These get stuck in my dog’s gums and then their teeth and they’re hard to digest. I stopped buying them and went to another brand, unfortunately. I thought maybe it’s a fluke and the back got shook up, but I’ve ordered at least eight bags.
