I have given Timber a bit of peanut butter, and God knows how much Leather's gotten after all of her kitchen raids

I'm not sure about the raw eggs though. A friend of mine gives his husky raw eggs every morning to keep her fur shiny, but I do know for a fact that dogs can get samonella, and everyone should assume that all eggs carry it, for safety measure. I'm not sure how susceptible they are to it compared to humans, but maybe you should cook the egg just incase?
