Snowball is mainly kibble fed, with raw supplements a few times a month. He has eaten raw in the past for a few weeks and had no issues, even with a quick switch. Now... I've got two turkey wings sitting in my fridge that I bought on Monday, meaning to give to him, and I kept forgetting. They were packed on Feb 8 (a week ago) and they're just starting to get slimy. I looked into whether old meat is generally okay for dogs, and I found alternately that old meat should never be fed (i.e. don't feed your dog anything you wouldn't eat yourselves), and that old meat is just fine for raw-fed dogs. But I haven't really found anything about old meat for kibble-fed dogs. I'm tempted to just give him one, but I was wondering whether anyone feeding kibble has any experience with feeding meat on the riper side.
