Check the instructions first
Before opening a new recipe, read its package directions and check whether your veterinarian has given your pet a specific transition plan. Follow those instructions when they are available.
Let the change be gradual
If you do not have a specific schedule, avoid changing foods all at once. Introduce the new food in small steps and adjust the pace to the package guidance and your pet’s response. There is no single schedule that fits every animal or food.
If you notice a concerning or ongoing change while switching foods, pause the transition and ask your veterinarian what to do next.
Keep the details close
Note the old and new food names and when you began the change. Those details can make it easier to follow the directions or explain the situation if you contact your veterinarian or the food maker.
