There are many disgusting things included in some dog food. Please take the time to choose a proper food. One helpful tip: if the main protein source is listed as a non-specific "meat" then stay away from it. This usually includes roadkill (I'm serious!), rotting meat from the grocery store shelf, styrofoam and all, animals that died from diseases like cancer and worm infestations. Even if it's a decent source of meat used (but don't count on it), it may be an animal that at some point was treated with antibiotics or growth hormones. That's just not okay. I hope this article has been helpful. I would encourage you to do more research on dog food brands and get suggestions from trusted sources. Good luck!
