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.

Perfect for small dogs!
Flavor Name: Peanut Butter, Size: 55 Count (Pack of 1)
My toy poodle loves these little sticks. They are small and easy for him to chew, and he loves the peanut butter flavor. The twists are high quality, according to my pup! He gets one a day, and he looks forward to treat time. The snack is perfect for a treat because it does not keep him from eating his food.
