how to switch your dog's food

Your vet may have recommended a new food or you may just be thinking about changing your dog’s food to something new. There are “right ways” and “wrong ways” to change the food and we will give you recommendations below on the very best way. To make it extra easy for you, we will share a day-to-day schedule of how to change your dog’s food.

Sudden changes in dog foods – even from one very good food to another good food – can cause gastrointestinal upset in some dogs. There are dogs that do fine with a total fast change but other dogs will have problems. The most common symptom a dog will exhibit is diarrhea. The next most common symptom is vomiting. And some dogs will have both vomiting and diarrhea.

The best thing to do is to prevent a gastrointestinal upset by following the recommendations below on how to change your dog’s food.

How to Change Your Dog’s Food 

The key to changing a pet’s food is “slowly!”

The best way to start a new food for your dog is to begin by mixing a small amount of the new food in with the original food and do this over several days. Gradually increase the percentages over 10 days until you are feeding almost all new food then make the final switch.

For example, here is a schedule of how to change your dog’s food over 10 days:

  • Day one – Feed 90% original food, 10% new food.
  • Day two, Feed 80% original, 20% new food
  • Day three – Feed 70% original, 30% new food
  • Day four – Feed 60% original, 40% new food
  • Day five – Feed 50% original, 50% new food
  • Day six – Feed 40% original, 60% new food
  • Day seven – Feed 30% original, 70% new food
  • Day eight – Feed 20% original, 80% new food
  • Day nine – Feed 10% original, 90% new food
  • Day ten – Feed 100% new food

You can accelerate this by doing it over 3 or 4 days but the ten-day transition works well in most dogs.
