I'm pretty excited to try these biscuits for my 'brothers' but I have two questions. Would this recipe work with rye flour? and what about refrigeration? I was hoping to mail them to my parents but don't want to make the dogs sick by not refrigerating them. thanks so much! Hi Michelle Rye flour should be fine, you might want to run the "is it safe for dogs" past your vet to be sure. If you bake the treats until they are very dry and ship 2nd day, they should be fine out of the fridge. ~ MaryJane
