PROBLEM: It's amazing how little popularity that Diamond Pet Foods seems to have considering the quality ingredients their foods contain!  I worked at a pet store for about four years. Our number one recommendations on foods were Natural Balance and Wellness- two EXCEPTIONAL foods that are pretty expensive.  But for those owners who have multiple dogs or even one large breed dog, those brands can cripple your budget.  So when I would get customers who absolutely LOVED their pets and wanted to be able to feed them healthy food without breaking their banks, I recommended Diamond.  Diamond dog food costs about the same as those commercial brands like Purina and Iams, but contains ONLY natural, healthy ingredients.  Just remember, the less garbage you feed your dog (by-products, fillers) the less your dog uses the bathroom- AND they stay fuller, longer! 
 Polarity: Negative

SOLUTION: False

PROBLEM: I have a slightly different version of this - different brand.  My son started using it around six months, and he really enjoys it.  He DOES get messy if he eats something sticky or juicy like banana or watermelon, but whatever...  Anyway, I also had trouble cleaning it, until I tried scrubbing it with a nail or vegetable brush.  That works pretty well.  It takes some time, but not as much as it would take to run food through a food mill or blender, or cut it up, then clean it up off him, the chair, the floor, the dog, me, well you get the picture. 
 Polarity: Positive

SOLUTION: True

PROBLEM: These pork rinds contain MSG which is not stated on the listing.  Deceptive listing for this product.  Will not purchase again.  Shame on Amazon for wasting my money.
