Rare diet..Bite off more food then he can chew..

[Im square and round]

I had to buy chicken backs by the case recently, a 40lb case.
I only have 1 dog, he weighs roughly 70 pounds. So he eats about 1.5lb of meat a day.
I'll be freezing the majority of the meat, but I have way too much meat for my freezer.

[question]I'm just wondering, are their any ways I could turn these chicken backs in to treats?[question] I neeo to clean space for other kinds of meat for him.

Ik people dry out the meat and make jerky out of it, but that isn't a option for me right now.

Eventually I'll be making soups outta the chicken backs, but I don't see myself using more then a couple of pounds for that..
