Some of the GSDs that I have owned have done this. Does not matter what you feed them. I feel that the dog gets ride of all waste so he can be at the top of his game. He is excited. Knows that activity is coming and wants to be ready. Early defecation can be the result. Some things I have tried that helped was feeding a little less, spreading out the feeding times and exercise times a little farther apart.
