IMO - Euk is not a very good food.
Here's my rule:
NO By-products (in any form of text)
NO Corn (in any form of text)
Absolute NO-NO = "Made in China" or "Not for Human Consumption"
May I suggest a few better quality foods, that have some taste to it:
Canidae
Wellness
Solid Gold
Natural Balance
Merrick
Try going to a few of those brands websites and check out what store's in your area carry them. Most of the time, they have samples for you to try some out.
