Recipe for crispy/crunchy dog biscuits with barley flour, meat, & oats? - barley dog

I cook for my dog, but she is allergic to white flour, wheat, rice and rye flour. She is allergic to barley or oats. I've tried to make cookies, but only out soft and sticky.

How do I get sharp, or you have a recipe for me?
