I made a batch of dog biscuits for a Christmas gift, and I want to write the dog's name on them with colored sprinkles.  The biscuits are the texture of over-baked sugar cookies.  Does anyone have an idea of how I can get crystal sprinkles to stick without using a sugar glaze?  Or another idea for a pretty way to put the dog's name on the cookies? 
You could use egg whites, well beaten, (from pasteurized eggs), and a fine tipped squeeze bottle or a narrow paint brush to apply it, then sprinkle and let it dry.
