I am sure you can get alot of different answers on this and Salmonella is sure to come up...Let me start by saying that dogs are not as suseptable to get Salmonella as people are and if that is a concern then cook the egg.....But I feed raw eggs and have never had a problem... Here is some detail on the issue of Salmonella......
Raw eggs are far healthier than cooked ones... especially if the cooked egg is cooked in oil or in fat.
The common concern on raw eggs are bacteria infection.... Salmonella, ever since it has been found inside a small number of eggs. Scientists estimate that, on average across the U.S., only 1 of every 20,000 eggs might contain the bacteria. Therefore, the likelihood that an egg might contain Salmonella is extremely small - 0.005% (five one-thousandths of one percent). Statistically, the incidence of salmonella in non-organic eggs is one in 20,000. The chance of infection works out to once every 30 years based on the consumption of a dozen eggs a week.
To protect the public at large, the Center for Disease Control in the United States recommends that eggs be cooked and vets were told to consider those guidelines.
Bacteria can sometimes accumulate on the shell. You should always wash the egg regardless of how you will feed it to yourself or your dog!
The odds are very small that you OR YOUR DOG would get sick from eating raw eggs. If you want to feel safer, use pasteurized eggs....Companies are pasteurizing eggs in the shell, so check the label.
The egg should be given whole and not seperating the egg/yolk due to the fact raw egg whites have avidin, but if you feed the whole egg, they don't get a biotin deficiency.
