This is a great discussion, and I've already posted some info on this topic in the "B.A.R.F. 101" thread.
While that study is dated about 10 years ago, there have been NO studies to disprove it since, even though scientists have tried.
Also, while we can agree that canine and human digestive systems are different in many ways, there is no proof that the canines are NOT effected the way humans are by the avidin found in raw eggs. Therefore, I feel it is best for me to feed my dogs hardboiled eggs.
I am living proof that cooked eggs are better for humans than raw eggs. I'm an athlete, and I go through about 7 dozen eggs a week to help me meet my protein intake requirements. For years, I was putting raw eggs in my shakes, even though other athletes were preaching to me about the benefits of cooking them. After getting Salmonella, I switched to cooked, and the changes to my body have been very noticeable. I now have more lean muscle tissue and I'm much stronger because my vitamin B6 levels are now higher AND my body is absorbing all of the muscle-building protein.
In conclusion, since I do know how beneficial it is to cook eggs for human consumption based on scientific data and my own personal experience, I will also cook my dogs eggs until someone can show me scientific proof that the avidin found in raw eggs does not effect canines the way it effects humans.
