When we switched to TOTW their was no puppy formula, so we fed the adult to our pup, but I am not sure of the difference. Our girls like all of the TOTW flavors except the pacific stream, but I don't know what that means. We do like TOTW, the different flavors keep the girls happy and we are very pleased with their coats and energy. Good Luck
