It’s a world most of us will never know, so why not believe? Plenty of American heroes, a great WWII yarn, and mankind is saved. The boy and the girl find each other.

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:
Awesome! awesome awesome awesome. Nicely painted, its nifty the way it folds up and it rolls great! Does not feel cheap at all and it actually handles the weight of pantry canned foods when I reorganized things. I look forward to utilizing this some more in my home.

Ex Output:

positive
