Eggs are fine in a dog's diet occasionally
But don't think that as small Yorkie is ever going to be eating what you would consider a lot
I have found them to be VERY finicky
My two turn up their noses to everything that they have seen before
I am constantly trying to find new things to mix with their puppy food
and soetimes they will PICK OUT THE PUPPY FOOD to get to whatever I mix in there

I'll go in to find kibble all over the floor and the puppy dish empty
