I never feed a dog before work.
Eggs are a valuable source of protein, but should be lightly cooked by cracking them into hot water, and letting them stand for about a minute, until the egg whites start to turn white.
This destroys most of the avidin that binds the biotin in them.Eggs will not. make a dog loose,but too many can have the opposite affect.
I used to give a dog a couple of eggs after a hard days coursing,cracked in a cup with hot water on them,it assists in muscle protein rebuilding,and the hot water helps the digestion of the eggs without damaging the protein and nutritiona
