Eggs are rich in natural sulphur, what some people take in another form, call MSM. Along with high quality protein, a egg is rich in sulphur that helps the joints and getting over the soreness and stiffness in the early parts of the keep. Best to give boiled and not raw. Raw eggs over time can create a certain vitamin or mineral deficiency. Which one and what I am no longer sure about. Given over no longer than say 12 weeks raw, may not be long enough to create a problem.

Usually one to two eggs is plenty enough. Little dog one and med to big dogs two. Cheers.
