Good stuff with some minor caveats
Flavor Name: Beef, Size: 1.5 Pound (Pack of 1)
My dog generally loves these. They seem to be a good quality ingredients. I think he likes the taste, but do know that they have a very smoky smell. I don’t know how fresh jerky can be, but they do seem like a very good value for the money. Another brand sells dog jerky as human quality. And my dog also likes that. The other brand is much softer, and this brand, wag, is a bit harder. So perhaps, if you have an older dog or a dog with teeth issues, this might not be the best choice.

Tasty treats, but don’t like the size.
Flavor Name: Beef, Size: 6 Ounce (Pack of 1)
Dogs loved them, and it’s a great price for the amount of ounces you receive, but the individual pieces are too big - only 8 total in the package. I break them in half for my two dogs.
