What Percentage to Use When Transitioning Dog Food

Begin with approximately 25% new dog food and 75% old food. Gradually increase the new food over seven days while monitoring your dog’s appetite, stool quality, and comfort.

For days one and two, serve 25% new food and 75% old food. Use 50% of each food on days three and four, then 75% new food and 25% old food on days five and six.

On day seven, serve 100% new dog food if digestion remains normal. Measure portions by weight or with the same scoop so the daily calorie amount does not accidentally increase.

Pause at the current ratio if your dog develops mild gas or soft stool, and extend the transition to 10–14 days. Contact a veterinarian if vomiting, persistent diarrhea, appetite loss, blood in the stool, or lethargy occurs.

Compare feeding directions because two formulas can have different calories per cup. Dogs with allergies, sensitive stomachs, or prescription diets may require a veterinarian-directed schedule rather than the standard percentages.

Keep treats and table scraps consistent during the transition so you can identify how the new formula affects your dog. See the complete seven-day guide to changing your pet’s food safely for a step-by-step plan.

Check the listed dimensions for plan the change carefully against the available vehicle space before use.
