There are several reasons why you may need to change to a new food brand or formula:

You want to put them on a different formula

Your pet has a food allergy or sensitivity

Your pet is entering a new life stage

Your pet needs to gain or lose weight

Your veterinarian has recommended a specific diet for your pet

You want to change your pet to a function or minimally processed food

When transitioning to new pet food, do so slowly for about 7–10 days, mixing an increasing amount of food with old food each day:

Start with 75% old food mixed with 25% new food for approximately three days.

Then mix 50% old with 50% new for three days.

Then 75% new, 25% old for three days.

Then 100% of the ration will be the new dog food.

Do consult your veterinarian Portland, OR before making any changes to your pet's diet.
