Transition Instructions

You may be anxious to make the switch to a new food, particularly if the new food will help address any issues your dog is having. A gradual transition is the best way to switch to a new food, though.

We recommend making the switch over a 7- to 10-day period. This gives your dog (and his stomach) a chance to adjust to the new food.

Here’s our 7- to 10-day plan for switching dog food:

Days 1 to 2: Feed 3/4 of the normal amount of current food and add 1/4 of the new food. Days 3 to 4: Serve half the current food and half the new food. Days 5 to 7: Feed 3/4 of the new food and 1/4 the previous food. Days 8 to 10: Serve only the new food.

If your dog doesn’t seem to like the new food or if he experiences digestive upset, extend the transition over a few more days. You can also ask your veterinarian for advice.
