[EX Q]: 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 A]: positive

[EX Q]: These definitely do not feel safe. I was baking something at 400F and took the tray out and looked at the mitt and it was completely black where I picked it up..... NOT WORTH BUYING.
[EX A]: negative

[EX Q]: These guys sent the jersey to California. I live in New Mexico. I sent them an email about the situation and they said they would refund my money by putting $10.00 back to my card. I emailed them a screenshot of the Jersey and actual price. No reply.
[EX A]:
negative
