When Priscilla Feral sent out her latest cookbook for testing she knew the routine. Explains Feral, “You think, ‘Okay the recipes are reliable. I know they work. I’ve tossed the ones that are unpredictable.’” The author is the director of Friends of Animals, and she has written two vegan cookbooks for people. But For the Love of Dog Biscuits is her first cookbook for dogs. That meant the 19 testers from all over the country that went to work on Feral’s recipes would not be able to tell her what they didn’t like. “Imagine having your recipe bomb over a dog that’s hard to feed and you have no idea why,” says Feral.
