Glad you mentioned "doggy treats" Semi...
I always take the sinewy strips and the leathery exterior strips that I take off my cuts and dehydrate them for "doggy jerky". I also take a lot of the clean but gristly or gnarly chunks that get trimmed off and run them them through my grinder after I've ground my own good stuff so our little spoiled rotten Jack Russel Terrier gets her own jerky and burger from each deer we kill!!
