Abrupt diet changes are a leading cause of vomiting and diarrhea in dogs. A gradual transition over 7–10 days helps the digestive system adapt.

Key Points

  • Days 1–2: 25% new food, 75% old food.
  • Days 3–4: 50/50 mix.
  • Days 5–6: 75% new, 25% old.
  • Day 7 onward: 100% new food — extend each stage if stool softens.

Practical Tips

  • Change only one food variable at a time.
  • Pause the switch and call your vet if you see blood in stool or repeated vomiting.
  • Wet and dry foods can be transitioned using the same percentages.
