How to Switch Your Pet's Food the Right Way
A gradual transition isn't just a suggestion — here's why it matters, how to do it, and what to reach for if your pet needs a little extra support along the way.
Why your pet needs time to adjust
When changing or upgrading your pet's food, its digestive system needs time to adjust. A gradual switch reduces the chance of loose stools, gas, or stomach upset.
Dogs heavily rely on their sense of smell to identify what they eat. Introducing a new scent into their diet can initially lead to hesitation or reluctance — it's not just about taste, but also their instinctive response to something unfamiliar in their bowl.
Another significant factor is gut health. Dog digestive systems become attuned to a specific type of food over time, developing a unique gut bacteria balance. Introducing a new diet abruptly may disrupt this balance, leading to digestive discomfort or sensitivity. A gradual transition gives their system time to adjust to new ingredients and compositions.
"Every pet is unique — the transition could go easily or take a bit longer, and that’s perfectly okay."
Your 7–10 day transition plan
Start by mixing the new food in with what you’re currently feeding, then slowly build up until the new food is the sole food you’re feeding. If your dog has a sensitive stomach, extend the transition over a longer period. Even if your dog isn’t eating their current diet enthusiastically, it’s still important to start small with new food — sudden changes can cause digestive upset.
| Period | Old Food | New Food |
|---|---|---|
| Days 1–3 | 75% | 25% |
| Days 4–6 | 50% | 50% |
| Days 7–10 | 25% | 75% |
| After Day 10 | 0% | 100% ✓ |
Transition & digestive aids
We recommend adding a digestive aid daily throughout the full transition period — especially helpful in the first several days. Plain pumpkin is a simple, natural option rich in soluble fiber that helps regulate digestion in both directions. We also carry several great products to support your pet during the switch:
Probiotic sprouts

Digestive support
Ask a team member for a recommendation based on your pet’s specific needs and the food you’re transitioning to.
For pumpkin, a general daily serving guide:
| Pet Size | Daily Amount |
|---|---|
| Cats & Small Dogs | ~1 teaspoon per day |
| Medium Dogs | ~1–2 teaspoons per day |
| Large Dogs | ~1 tablespoon per day |
What to watch for
A little soft stool in the first few days is normal. If your pet experiences any of the following, slow the transition down and give us a call or stop in — we’re happy to help:
- Vomiting
- Significant diarrhea lasting more than 2 days
- Complete refusal to eat
Frequently asked questions
Do I still need to transition when using a topper?
Yes — when adding a topper, introduce it slowly, working your way up to the feeding guidelines on the packaging. If the topper is a complete and balanced meal (this varies by product and manufacturer), a full slow transition is necessary. It’s also important to decrease whatever you’re currently feeding when adding a topper, so you don’t overfeed your pet at mealtime.
My dog just transitioned to a new brand. Do I need to transition between recipes within that brand?
Typically not. If your dog is fully transitioned to a food type, switching to a different recipe within the same brand usually doesn’t require a full transition. That said, if your dog tends to be sensitive to dietary changes, introducing the new recipe more slowly certainly won’t hurt.
Should I rotate proteins and recipes? If so, how often?
If your dog or cat doesn’t have food allergies or sensitivities, rotating proteins — a practice called rotational feeding — is a fantastic idea. It can help prevent intolerances and allergies from developing, decrease mealtime boredom and picky eating, and increase the variety of amino acids your pet consumes.
We suggest feeding one flavor for 2–6 weeks, then switching to a different flavor for 2–6 weeks, and so on. For an average dog or cat, no transition is typically needed between flavors within a brand.
Are the transition guidelines different for cats?
Cats share the same general transition timeline as dogs, but come with their own quirks. Cats have the Three T’s — Taste, Texture, and Temperature. If even one is off, a cat may refuse to eat. A few tricks that can help:
- Experiment with format — try dry vs. wet, freeze-dried vs. frozen.
- Use your hands — rub the new kibble in your hands and pet your cat. They’ll groom themselves, getting familiar with the new scent before it shows up in their bowl.
- Let them “find” it — sprinkle a few pieces in their favorite spot so they discover it on their own terms rather than being “fed” it.
Cats are creatures of habit, so the transition may take longer than a week — and that’s completely normal.
