Same here - frozen and has freezer burn? PHSAW just some extra flavour for the dog!
If it's got that "off smell" but isn't green, I'll offer it to Ky ... if she doesn't take it, then I toss it. While lots of dogs will eat rotten meat (I mean heck, they eat deer and rabbit poop), I know that Ky won't, so I'm safe.
One of the things you can do is buy the past date meat in bulk and freeze it as soon as you get home. Then it will last a while!
