Max is so cute!!!
I put peanut butter in my dogs' kongs, and they love it--I have no idea how much is too much though.
I have heard of the raw egg thing, but I don't give it to my dogs--Kito (my Shiba), used to eat mackerel every 2 weeks to shine up his coat, but I couldn't handle the smell anymore
I had thought about the eggs, but I thought I might just scramble them up and give them to the dogs--at least they're cooked that way--but I don't know if they loose any nutrients after being cooked.
