Question: 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.

Answer: positive

Question: A simple book and it works! I bought it when my toddler was 2.5 yo, after visiting a friend's home and he didn't understand why he couldn't have my friend's breastmilk. After reading this book a few times, he got it. It explains a simple message, if it's not your mama then her milk is not for you. He understood right away why couldn't he have another human mama or animal mama's milk.

Answer:
positive
