Example Input: I have 2 husky/shepherd mixes. The first is 13 months and has a finicky stomach - if he eats too fast, drinks too fast, or eats anything out of his routine, he would bring it back up. He also wouldn't eat more than a few nibbles at a time. The 2nd is 7 months old and came to us with severe diarrhea (vet's food didn't fix it either). He would eat anything and everything if we let him. Within a day of both dogs being on Harmony Farms (No fasting, just a quick switch), both dogs digestive issues are gone. My oldest (the finicky eater) is healthily eating his meals without pause or hesitation. My youngest has solid, regular bathroom breaks and has been able to relax his water intake as a result. They're both more relaxed. We purchase at our local grocery store (Hannaford here in NY) for about $1.31/lb. For the price, ingredients, and results - you can't beat it.

Example Input: Good quality nectar.  Very tasty.  However, I was expecting 46 fluid ounces, not 46 ounces in weight.  I find that 46 ounces in weight makes about 32 fluid ounces.

Example Input: I thought I was getting a healthy alternative to cheese its and cheese nips. But after comparing the labels, I was surprised to see that the Back to Nature ones have basically the same ingredients (nothing organic) and MUCH MORE sodium than the major brands.  Seems they just put regular crackers in a 'healthy' looking box and got away with charging a premium.
