How to Transition Your Dog to a New Food Safely

Switching your dog’s food too quickly can result in digestive distress—diarrhea, vomiting, or refusal to eat. Here’s how to do it the right way.

Why Transition Slowly?

A dog’s digestive system adapts to food slowly. A sudden change can disrupt gut flora and irritate the stomach lining.

The 7-Day Transition Plan

Day Old Food New Food
1–2 75% 25%
3–4 50% 50%
5–6 25% 75%
7+ 0% 100%

Watch for Signs of Trouble

  • Loose stool or diarrhea
  • Excessive gas
  • Vomiting
  • Lethargy or loss of appetite

If symptoms persist, revert to the old food and consult your vet.

Pro Tips

  • Feed at regular times
  • Keep portion sizes consistent
  • Mix with a bit of warm water or low-sodium broth to encourage appetite
