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.
positive

The connection with my iPhone was very smooth and easy. There is no lag and the sound quality is superb. It last days with full charge. Looks very sophisticated.
