How to Switch Dog Food: A Gentle 7-Day Transition Plan
Quick answer: Change a healthy dog’s food gradually over about seven days: begin with mostly the old food, increase the new food every two days, and slow down if stools soften. Puppies, seniors, dogs with disease, and pets changing to a therapeutic diet need an individual plan from a veterinarian.

What matters most
- Days 1–2: about 75% old food and 25% new food
- Days 3–4: about half of each food
- Days 5–6: about 25% old food and 75% new food
- Day 7 onward: the new food, if appetite and stool remain normal
Before you buy
- Confirm the new food matches species and life stage
- Compare calories per cup or per 100 g before copying the old portion
- Keep meal times and treat intake stable during the change
- Record stool, appetite, vomiting and itching
Common mistake to avoid
Do not use a gradual transition to delay care when a dog is repeatedly vomiting, has blood in stool, seems painful, or refuses food and is unwell.

Frequently asked questions
Can I switch faster?
Some dogs tolerate a faster change, but a gradual plan makes digestive reactions easier to spot.
What if diarrhoea starts?
Pause the increase, keep water available and contact your veterinarian if signs are severe, persistent or accompanied by lethargy.
Should portions stay identical?
Not necessarily. Foods have different calorie density, so compare the label and your dog’s calorie target.
