This is interesting. I was just reserching this question last week. There seem to be two schools of thought about this.
One school says: You can give a raw ORGANIC egg OCCASIONALLY. But continual use of raw eggs will cause the coat to become worse because it leads to a biotin deficiency. Raw egg whites contain avidin, an enzyme which ties up biotin (makes it unavailable for absorption into the body). Symptoms of biotin deficiency include dermatitis (inflammation of the skin), loss of hair, and poor growth. Stick to scrambled eggs
The other school says: It's fine, and the yolk ofsets any problems the white might cause.
I'm not sure, but have been giving our B puppies scrambled eggs for the moment.
