Yes yes yes! Low calorie w/ no garbage ingredients
Size: 1 lbs
I am super picky when it comes to dog treats. Do my research and this treat has proven to be a great find for my pup. The minimal ingredient list is fantastic and there is no crap that shouldn’t be there. They are smaller pieces but look fresh and my dog cannot get enough! They are low calorie and great alternatives to other treats sold with fillers and chemicals that harm our fur babies! Highly recommend these. My dog eats them with vigor! Healthy snacks!

Great one ingredient treats
Size: 1 lbs
I love that these are one ingredient treats. The quality is great, my dogs love the taste, and their appearance looks great without a bunch of additives. The texture is nice and the ridges in the cuts do help with cleaning my dogs teeth a bit. They are fairly expensive for what they are. These are great if you don’t have the time to make your own.
