What Should I Feed My Dog After They've Been Sick?

At a glance

• Withhold food for 2–6 hours after vomiting to let the stomach settle — always keep fresh water available.
• Start with small, frequent portions of bland food: plain cooked chicken or white fish with plain boiled white rice.
• Reintroduce normal food gradually over 3–5 days, mixing bland and regular food in increasing proportions.
• Avoid fatty foods, dairy, rich treats, and anything heavily seasoned during recovery.
• Persistent vomiting lasting more than 24 hours, blood in the vomit, or vomiting alongside lethargy or pain requires veterinary attention immediately.

What should you actually feed a dog after they've been sick?

After vomiting, start with a short food fast of 2–6 hours, then offer small amounts of bland, easily digestible food. The goal is to give the gut a chance to settle before asking it to process a full meal.

The classic option is plain boiled chicken breast with plain boiled white rice, roughly in a 1:3 ratio (one part chicken to three parts rice). White rice is low in fibre, which means it moves through the digestive system gently and doesn't aggravate an already irritated gut. Plain white fish is an equally good alternative, and some dogs find it easier to stomach than chicken.

Portion size matters as much as food choice. Offer around a quarter of the dog's normal daily portion in the first sitting. If they keep it down, offer another small meal three to four hours later. Spreading meals across the day reduces the load on a recovering stomach. After 24 hours without further vomiting, you can begin moving back toward their normal diet.

Dogs recovering from a bout of sickness often benefit from food that is gentle on the gut — how diet connects to common health conditions, including digestive upsets, is worth understanding as part of your dog's long-term health picture.

How do you transition a dog back to their normal food after illness?

Transition back over 3–5 days, not all at once. A sudden return to a full normal diet after illness can trigger a second round of vomiting or diarrhoea, even if the original cause has resolved.

A simple day-by-day approach:

• Days 1–2: 100% bland food (small, frequent meals)
• Day 3: 75% bland food, 25% normal food
• Day 4: 50% bland, 50% normal
• Day 5: 25% bland, 75% normal
• Day 6 onwards: back to full normal diet if no further symptoms

If your dog's normal food is a high-quality, easily digestible option to begin with, the transition back tends to go more smoothly. Foods with whole, identifiable ingredients and no fillers are gentler on the stomach than heavily processed options with long additives lists. Marleybones Chic Chicken, for example, uses freshly prepared chicken as the primary ingredient, slow-cooked in-pack without preservatives, which makes it a practical choice for the reintroduction phase.

What foods should you avoid giving a sick or recovering dog?

During and immediately after illness, several foods make recovery harder or actively cause further problems.

Avoid these during recovery:

• Fatty foods — high-fat meals stimulate the pancreas and can worsen nausea or trigger pancreatitis in susceptible dogs.
• Dairy — most adult dogs are lactose intolerant to some degree. Milk, cheese, and yoghurt irritate an already sensitive gut.
• Rich treats and chews — rawhide, pigs' ears, and high-value chews are hard to digest and best avoided for at least a week.
• Heavily seasoned or spiced food — anything cooked with onion, garlic, or strong seasoning is toxic or irritating to dogs.
• New proteins they haven't eaten before — introducing a novel ingredient during recovery adds an unnecessary digestive variable.

Stick to familiar, simple foods until your dog has had at least 48 hours of normal stools and normal energy levels.

When should you be worried about a dog that keeps being sick?

Single episodes of vomiting in an otherwise well dog are rarely cause for alarm. Dogs vomit relatively easily compared to humans, and a one-off incident often resolves with a short food rest and bland feeding.

Call your vet if you notice any of the following:

• Vomiting continues for more than 24 hours
• There is blood in the vomit (fresh red blood or dark, coffee-ground material)
• Your dog is also lethargic, in pain, or has a distended abdomen
• They are unable to keep water down
• A puppy, senior dog, or dog with a known health condition is sick more than once

Repeated vomiting in combination with diarrhoea can lead to dehydration quickly. In small dogs and puppies especially, dehydration becomes dangerous within hours. This is when veterinary input is essential rather than optional.

Once your dog is fully recovered, it is worth reviewing whether their regular diet is working for them. Dogs that vomit frequently, have loose stools, or seem gassy after meals often benefit from a diet with higher-quality ingredients and no added fillers. Every dog is different — build your personalised Marleybones feeding and health plan tailored to your dog's age, size, and health requirements.

For dogs who seem to have an ongoing sensitive stomach rather than a one-off illness, understanding what to give dogs for diarrhoea can help you act faster and more confidently next time.

Frequently asked questions

How long should I wait before feeding my dog after they've been sick?

Wait 2–6 hours after the last episode of vomiting before offering food. This gives the stomach lining time to settle. Always keep fresh water available throughout — hydration is more urgent than food in the short term.

Can I give my dog plain rice on its own after vomiting?

Plain boiled white rice on its own is fine as a very short-term option, but it lacks protein and is not nutritionally complete. Pair it with plain boiled chicken or white fish to give the gut something to work with while still keeping the meal gentle and easy to digest.

Should I give my dog probiotics after they've been sick?

A probiotic supplement can help restore the balance of beneficial bacteria in the gut after illness, particularly if your dog was given antibiotics. Speak to your vet about which strains are most appropriate. Some complete dog foods include prebiotic ingredients like chicory root, which supports gut bacteria as part of the daily diet.

Is it normal for a dog to not want to eat after being sick?

Yes. A reduced appetite for 12–24 hours after vomiting is completely normal. Do not force food. Offer a small amount, remove it after 20 minutes if untouched, and try again a few hours later. If your dog refuses food for more than 24 hours or shows other symptoms, contact your vet.

Can I feed Marleybones meals to a dog that is recovering from illness?

Once a dog has passed the initial bland food phase and is ready to transition back to their normal diet, a high-quality, minimally processed food like Marleybones is a sensible choice. The meals are made with whole, freshly prepared ingredients and no fillers, which makes them straightforward for a recovering gut to process. Introduce them gradually, as you would any return to normal feeding.
