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.

Dog LOVED these treats ...
Flavor Name: Beef, Size: 1.5 Pound (Pack of 1)
Dog LOVED these treats - I LOVED the fact you can portion it out as you want. They come in soft strips which are easy to manage & portion out. Great value overall ...

My dogs think these are actual steak bites
Flavor Name: Beef, Size: 1.5 Pound (Pack of 1)
I’ve tried a lot of treats and my dogs usually get bored after a while, but they go crazy every single time I grab this bag. The pieces are soft and easy to break apart, which is perfect for training or smaller bites. I also like that they don’t smell horrible like some jerky treats do. My picky dog even listens better when I have these in my pocket, so that says a lot. Great size bag for the price and they stay fresh — definitely a repeat buy in our house.

Good if your dog’s not picky
Flavor Name: Beef, Size: 6 Ounce (Pack of 1)
I ordered two treats. One was the beef because thought I’d give it a try. It looks good. Smells good, but not a hit with my dogs. It’s really soft and they like just a little bit harder too, but for little dogs are medium that are not too picky. I would definitely get this for them if they want something other than a chicken treat.
