What to Feed Your Dog When You Run Out of Their Usual Food

At a glance

• Plain cooked chicken or white fish with boiled white rice is the safest short-term stop-gap for most healthy adult dogs
• This combination is not nutritionally complete — it works for 24 to 48 hours, not longer
• Avoid onion, garlic, grapes, raisins, and anything seasoned — these are toxic to dogs
• Switching food abruptly can cause loose stools — transition gradually when returning to their normal food
• Puppies, senior dogs, and dogs with health conditions need a complete food restored more quickly

So you've run out of dog food — what can you actually give them right now?

Plain cooked chicken with boiled white rice is your best immediate option. It is easy to digest, unlikely to cause a stomach reaction, and most dogs will eat it willingly. White fish such as cod or haddock works just as well. Either way, keep it simple: no butter, no seasoning, no sauces.

The ratio to aim for is roughly two parts rice to one part protein. This keeps the meal gentle on the digestive system and provides enough energy to get through the day.

This is not a long-term solution. It is missing key vitamins, minerals, and fatty acids that dogs need. A day or two is fine. Beyond that, you are creating deficiencies — and understanding what a nutritionally complete meal actually contains makes it clear how much a plain home-cooked plate misses.

Puppies are more vulnerable here. Their nutritional requirements are higher and more specific, so if you have a young dog, prioritise getting a complete food back in front of them quickly. The same applies to dogs managing a health condition or recovering from illness.

What foods from your kitchen are safe — and what should you avoid?

Several everyday ingredients are safe for dogs in a pinch. Others are not, and some are actively dangerous.

Safe options to use as a temporary meal base:

• Plain cooked chicken (no skin, no bones)
• Plain cooked white fish such as cod, haddock, or pollock
• Boiled white rice
• Plain cooked sweet potato or regular potato (no butter or seasoning)
• Plain scrambled egg (no milk, no butter)
• Plain tinned fish in spring water — sardines or mackerel, not in brine or oil

Foods to avoid entirely:

• Onion and garlic (in any form, including powder) — toxic to dogs
• Grapes and raisins — can cause kidney failure
• Anything with xylitol, an artificial sweetener common in peanut butter and baked goods
• Cooked bones of any kind — they splinter
• Avocado, macadamia nuts, chocolate

Leftovers from your own meal are rarely a safe choice. They tend to contain garlic, onion, salt, or other seasonings that cause problems even in small amounts. Prepare something fresh for your dog specifically, even if it is just boiled chicken and rice from scratch.

Can you use another brand's dog food as a short-term substitute?

Yes — any complete dog food will do the job in the short term, even if it is not what your dog normally eats. If a friend, neighbour, or family member has a bag of their dog's food going spare, that is a perfectly sensible option.

The key thing to know is that switching food without a gradual transition can cause digestive upset — loose stools, a gassy stomach, or reduced appetite. For a one or two-day bridge, most dogs will handle it without issue. But if the substitute food is going to run for several days, mix it in gradually rather than switching in one go.

Marleybones Pantry Fresh meals are worth keeping as a backup for exactly this situation. They are shelf-stable without refrigeration or freezing, so a spare pack stored in the cupboard means you always have a complete, vet-developed meal on hand. The Chic Chicken or Boss Beef are good all-rounder options that work for dogs of all life stages, including puppies.

How do you transition back to their normal food without causing a stomach upset?

Once you have their usual food back, do not switch in one go. Even a 48-hour break from their normal food can make a sudden return harder on the digestive system than you would expect. A sensitive stomach is particularly susceptible to this.

A simple transition over three to four days works well. Start by mixing roughly 25% of their usual food with 75% of the temporary food on day one. Move to 50/50 on day two, then 75% usual food on day three, and fully back to normal by day four. Adjust the pace if you notice any loose stools or signs of discomfort.

If your dog seems off their food during or after the transition, give it a day before worrying. Dogs are sensitive to change and some will be reluctant eaters when their routine is disrupted. If they are not eating at all after 48 hours, or if they are vomiting or showing signs of distress, speak to your vet.

FAQs

How long can a dog go without food?

Healthy adult dogs can go without food for 24 hours without any harm. Beyond that, it becomes uncomfortable rather than dangerous for most adults, but puppies, senior dogs, and dogs with health conditions should not go without food for more than 12 hours. Always ensure fresh water is available at all times.

Is it safe to give my dog bread as a temporary food?

Plain white or wholemeal bread is not toxic to dogs, but it offers very little nutritional value and is high in carbohydrates. It is not a substitute for a proper meal. A small amount will not cause harm, but do not use it as a meal replacement. Bread containing seeds, dried fruit, or garlic should be avoided entirely.

Can I give my dog cat food if I run out of dog food?

Cat food is not toxic to dogs, but it is not formulated for them. Cat food is much higher in protein and fat than dogs require and can cause stomach upset or loose stools. A single meal of cat food in a genuine emergency is unlikely to cause lasting harm, but it should not become a habit.

Is Marleybones suitable to use as a substitute if my dog normally eats kibble?

Yes. Marleybones Pantry Fresh meals are complete and balanced for all life stages, so they provide everything a dog needs nutritionally. Because fresh food is a different format to dry kibble, some dogs with more sensitive stomachs may do better with a gradual introduction. For a one to two day stop-gap, most dogs handle the switch without issue.

What should I keep in the house to avoid being caught without dog food?

A spare pouch or two of a shelf-stable complete food is the most practical backup. Unlike wet food in tins or fresh-frozen options, Pantry Fresh meals from Marleybones do not need a freezer and have a long shelf life, so they sit in the cupboard until you need them. Beyond that, plain tinned fish in spring water and white rice are sensible kitchen staples that can cover a single emergency meal.
