Here's from the vets and biologists I know who feed homeade or supplement with whole foods: Egg white contains avidin, which binds with biotin and makes it unavailable to your dog (or cat). Egg white must therefore never be fed
alone unless cooked to the opaque stage, which breaks down avidin. Feeding it together with the rest of the egg is fine, however, because the yoke contains much more biotin than the avidin can bind. Ie, the yolk's biotin will bind all the avidin and still have more than enough for the dog's needs. Even without taking into account any biotin also contained in the dog's other rations.
Show breeders have been using raw egg for generations to put an extra deep glow in the coat of long coated breeds and a sparkle in the eye of any dog, whether for show or work. The original
Come Home Lassie, set in the Borders and Scotland in the 30s, describes this in a couple different places. Raw egg and warm thinned milk for a sick dog, and egg two to three times a week to gear up for a show. [sm=wink2.gif]
Old shepherds I've talked to, also describe the value of raw egg as a cheap source of supplemental protein for hunting and working dogs. Fish, egg, oat or barley meal, and raw butchers' bones was the traditional diet of the UK shepherd's dogs, and I've had excellent results reproducing it with some additional input from friends in animal medicine and science.
