I got to be honest my the dogs would eat any trash meat I made. I could trim all the connective tissue, fat and junk and cook it and they'd love it. I can't use them as taste abatures. But maybe, that trash is better than kibble? I haven't tried each, so I can't compare and only make assumptions.
I rendered deer fat one year and sliced the flank out of a buck. Nice flank strip, covered in deer fat on each side. Too hard to trim, but thought after rendering it would make nice dog bacon. As I was was cooking I was like "Damn, that looks good." Then I ate one and felt like someone cisco'd the roof of my mouth. Then I remembered "this is why I don't like deer fat!"
