you should do it over a 3 week period. i had to switch my pups food several times due to a food allergy and i have found that a change over in a 3 week period works best. some people might disagree.
you slowly add the new food as you minimize the old. i feed my dog a half a cup of food a day. i would figure out how many tablespoons are in the half cup. over a 3 week period i would figure out a schedule where i would remove one tablespoon old food and replace it with a tablespoon new food. you'd do this for a couple of days and then remove 2 tablespoons old food and add 2 tablespoons new. eventually, the new will out number the old and finally, by the end of 3 weeks, he's eating his new food. it's easier to chart it out on a piece of paper and leave it by his food bin. that way there's no second guessing yourself. the theory is that if you slowly introduce thenew food, you avoid diarhea and vomiting and constipation. their little bellies need time to adjust to anything new and if you do it too quickly you will have problems. hope this helps.
