I have been reading about adding raw eggs to dog food. We have soooo many eggs we get from our hens, that I have been adding one into the dogs food daily. I have found out some of them get the runs really bad with eggs, so they don't get them. As far as for the ones who can have them, I have read cook them, and don't cook them. I have read once a week only, and daily is fine. I have heard the yolks contain enough biotin to not matter with the whites, and I have heard the white destroys the biotin in the yolk. I am quite confused. What do all of you think about it? The ones of ours who eat the egg, look really good. I am not seeing any bad effects.
