I have fed my dogs Instinct Raw Boost for years. I have two big dogs, one with digestive issues, and then added a third big dog to my pack, so that brand of food was too expensive when I have to buy a 21lb bag every week or so. Dog Food Advisor gave this 5 stars, so I tried it. My problem dog didn't have any problems at all transitioning to this food, and my Great Pyrenees with allergies has had no issues. I am extremely pleased with this food. I would highly recommend it.

Ex Output:
positive


Ex Input:
I love these so much. The texture is so perfect. It has the chewiness of taffy without being sticky!! The flavors are amazing, and are natural fruit flavors, not weird artificial tasting at all. I love grape flavor the best!

Ex Output:

positive
