My labrador (Black Beauty) seems to hate egg . I have tried dog foods like Nutro Natural Choice, Purina Little Bites etc, which had been a success. But when it comes to raw egg, things are altogether different.
I just read somewhere on the internet that dogs should get cooked eggs but never raw. It was on one of those sites about foods etc that are toxic to pets. You might want to check out one of those sites just doing a general search and see what it says.
Some dogs don't like raw eggs. You don't have to worry about it, it's not nutritionally essential that your pup eat them. Eggs are not, however, toxic to dogs, regardless of whether they are raw or cooked. There is an ongoing debate regarding avidin/biotin that you may want to research. Moderation is the rule to live by, IMHO.
