ok... Here's the nutritional breakout.
Note: Since I don't have any doggie vitamins, I substituted 1/4 of a adult multivitamin.
The salmon is a good choice as it has a decent amino acid profile and has essential omega 3 fatty acids.
Egg whites are great sources of proteins and essential amino acids. I worry about salmonella tho. Check on the web and see how hot for how long you have to get them to make sure there are no salmonella left alive.
