How to Transition Your Dog to a New Food Safely
6-minute read · Reviewed against the Loyal Saints nutrition standard
Quick answer
To transition your dog to a new food, do it gradually over 7 days: start with 25% new food and 75% old food, then increase the new food by 25% every two days until you reach 100%. For dogs with sensitive stomachs, extend the transition to 10–14 days. A gradual change lets the gut microbiome adjust and minimizes digestive upset.
Switching foods too quickly is the most common cause of digestive upset during a diet change. The digestive system — and especially the gut microbiome — needs time to adapt to new ingredients. A gradual transition makes the switch smooth for the vast majority of dogs.
The standard 7-day transition
- Days 1–2: 25% new food, 75% current food
- Days 3–4: 50% new food, 50% current food
- Days 5–6: 75% new food, 25% current food
- Day 7 onward: 100% new food
For sensitive dogs
If your dog has a history of digestive sensitivity, extend each stage and stretch the transition to 10–14 days. Starting with a single, gentle protein (like the Loyal Saints Chicken formula) also helps.
What's normal vs. when to slow down
Normal: brief soft stool
A day or two of softer stool as the gut adjusts is common, especially switching off long-term kibble.
Normal: increased interest in food
Many dogs are noticeably more enthusiastic about real-food meals — a good sign.
Slow down: persistent loose stool
If loose stool lasts beyond 2–3 days, return to the previous ratio for longer before advancing.
Call your vet: vomiting or distress
Repeated vomiting, lethargy, or signs of pain are not normal transition effects — consult your vet.
When switching to Loyal Saints freeze-dried raw, rehydrate each portion with a little warm water and follow the schedule above. Most dogs transition easily, and within 2–4 weeks many owners notice improved coat, firmer stools, and steadier energy as the body adjusts to whole-food nutrition.

Frequently Asked Questions
How long should it take to switch dog food?
A standard transition takes about 7 days, moving from 25% new food to 100% in roughly 25% increments every two days. For dogs with sensitive stomachs, extend it to 10–14 days. A gradual switch lets the gut microbiome adjust and minimizes digestive upset.
Why does my dog have loose stool after switching food?
A day or two of softer stool is a normal adjustment as the gut microbiome adapts — especially for dogs coming off long-term kibble. If loose stool persists beyond 2–3 days, slow the transition by returning to the previous ratio. Persistent diarrhea, vomiting, or lethargy warrants a call to your vet.
Can I switch my dog's food cold turkey?
Some dogs tolerate an immediate switch, but a gradual transition is safer and reduces the risk of digestive upset for most dogs. Dogs with sensitive stomachs especially benefit from a slow 10–14 day transition.
How do I transition a dog with a sensitive stomach?
Extend the transition to 10–14 days, advance more slowly between stages, and start with a single, gentle protein such as the Loyal Saints Chicken formula. Rehydrate freeze-dried raw with warm water, and keep fresh water available. Consult your vet if your dog has chronic digestive issues.
