One or two a week is plenty for a little dog. If you smoosh up or grind the shell and include it, you don't have to worry about unbalancing the food. Just cook the white mostly. I do this by cracking the egg in a bowl (don't beat), and then sliding it into about an inch of boiling water in a little pan. Turn off the heat and let it sit until the white turns opaque. Then let the water cool and put the whole thing in your dogs' food! Slurpy-good fun. If you decide to sprinkle the egg shell on do it then. If you only feed an egg a week to a ten-pound dog then don't even worry about teh shell.
I do it this way because there's a bunch of a substance called avidin in the white, which binds up not only the small amount of biotin in the yolk, but also reserves in the body. Cooking disables the avidin, but if the yolk remains runny the biotin in it will stay available.
You can also cook it all the way through, any way you want. Biotin is the only real advantage (currently known) between cooked and raw eggs. Hard boiled eggs are a fun treat to take on the road - just stick them in a baggie in the cooler.
