Correct too much egg whites can cause a biotin deficiancy, but if you use an egg seperator and just feed the yolk or partially cook (soft boil) the egg it breaks down the advidin which is the cause of the biotin problem...I've always heard that too many raw eggs can lead to some kind of deficiency, although I always manage to forget what. (Biotin, maybe?) Plus they're very fatty, so if they aren't really needed, you're dumping a lot of calories in your dog. Moderation is key. I give raw eggs once in a while, usually mixed in with the kibble on a workout day. IMO, extra virgin olive oil is a better source of healthy fats. But again, that's JMO.
the shell is agreat source of calcium and proteinI have always given my dogs raw eggs. I usually crack them and give it to them over their kibble. Penny is allergic to eggs so she can't have any. She pukes everytime. Phoenix likes his right out of the shell. I just crack it and open it above his head he licks it all up. He loves it. Orion I have to put in his food.
Why do you give the dogs the shell along with the rest of the egg. I would just think since we don't eat it the dogs don't need to eat it either. lol. I don't mean to sound all humanish about that. Just wondering.
