Favorite treat
Flavor Name: Duck & Veggies, Size: 5 Ounce (Pack of 1)
My dog loves these treats the best, and the spoiled pooch has tried many! I love that these are super small sized, not messy, and low calorie which allows for lots of reinforcement while training. I also appreciate that the ingredients are very clean.

Buy these only if you love your dog
Flavor Name: Duck & Veggies, Size: 5 Ounce (Pack of 1)
I was looking for a dog treat that didn’t have sugar. And let me tell you these training treats are not only delicious to the dogs, but I love that the ingredients do not include any sweetener. I don’t think it’s a good idea to give our dogs tons of sugar, unless we’re brushing their teeth every day like we do for our own teeth. So for the longevity of my puppies teeth, she’s gonna get these high-quality yummy Yum‘s. I love that I can break them apart and make more treats out of the treats they gave so the bag last for months, even with daily training.

Perfection!
Flavor Name: Duck & Veggies, Size: 5 Ounce (Pack of 1)
Wonderful treat. My pups go wild and bounce around with pure joy. I have to hide the bag because these two figured out a whole MacGyver plot to snag them when I wasn’t looking. Cheeky little boys.
