Getting an Older Dog to Eat

An older dog going off their food worries owners more than almost anything else, and rightly — it is one of the most useful early warnings there is.

The right order is: find out why, then make eating easier.

Rule out the medical causes first

Do not start a feeding programme on a dog who is nauseous or in pain.

Common causes in older dogs:

• Dental disease. Extremely common and frequently missed. The tell is a dog who approaches the bowl, starts, and backs off; drops food; chews on one side; or has bad breath
• Kidney disease. Nausea, increased thirst and urination, weight loss
• Liver disease
• Cancer
• Pain anywhere. A dog with neck, elbow or back pain may find bending to a bowl uncomfortable
• Nausea, from many causes. Signs are lip licking, drooling, gulping, eating grass, licking surfaces, and turning away from food
• Medication side effects. Very common — mention every drug your dog is on
• Cognitive dysfunction, where a dog forgets to eat or becomes confused at the bowl
• Reduced sense of smell, which is an ageing change rather than a disease but has a big effect

See a vet if appetite loss lasts more than a day or two, or comes with weight loss, vomiting, lethargy, increased thirst or a change in stool.

Unexplained weight loss in a senior dog is never just age.

Treat the nausea

This is the most under-used intervention, and it is frequently the whole answer.

Anti-nausea medication, gastroprotectants and appetite stimulants all exist for dogs, they work well, and many owners are never offered them because they describe the problem as “fussiness” rather than “he seems queasy”.

Ask specifically. A dog who feels sick will not be persuaded by warmer food.

Then make eating easier

Warm the food. Gently, to body temperature. This is the single most effective measure, and it matters more in older dogs because the sense of smell fades.

Add water or a little unsalted broth, which increases aroma and helps hydration.

Wet food over dry. More palatable, more aromatic, and considerably more water — which matters in older dogs generally and in kidney disease specifically.

Small, frequent meals. Four or five small ones rather than two large. A large bowl is off-putting to a dog with a small appetite.

Hand feed the first few mouthfuls, which often gets a dog started.

Feed somewhere quiet, away from other dogs and household traffic.

Non-slip mat under the bowl. Older dogs slip, and a dog who has slipped while eating becomes reluctant to return.

Check the height. For a dog with neck or elbow pain, a slightly raised bowl can help — though note that raised feeders are not recommended for deep-chested breeds, so it is a judgement rather than a default.

Soften dry food with warm water and let it stand, for a dog with dental disease — though the mouth still needs treating.

Toppers, used carefully

A small amount of something aromatic mixed thoroughly through can restart a dog.

Good options: a spoon of wet food, plain cooked chicken, mashed sardines, plain tinned pumpkin, a little unsalted broth.

The rule: the same topper, every meal, mixed in — not a different exciting thing each day, and not produced in response to refusal.

Why that matters: a dog who learns that not eating produces an upgrade will hold out for it. This is how a genuinely unwell dog’s medical problem turns into a permanent negotiation once they are better.

Keep it under ten percent of calories and subtract it from the meal.

Dogs on therapeutic diets

A common and genuinely difficult situation: a dog with kidney disease or another condition refuses the prescribed food.

Do not simply give up on it. Renal diets in particular extend both survival and quality of life more than most medications.

What to do:

• Tell your vet. There are usually several brands, in wet and dry, with different flavours and textures
• Transition much more slowly — two to four weeks. Kidney dogs form food aversions easily
• Do not introduce it while the dog is nauseous or in hospital. A dog who feels sick while eating a new food associates the two and refuses it permanently
• Ask about anti-nausea medication and appetite stimulants
• Ask which toppers are permitted — some are, and an approved one that gets the food eaten is better than a perfect diet that is not

Keeping weight on

For a thin older dog:

• More frequent meals
• Higher calorie density, if the condition allows
• Adequate protein. The old advice to restrict protein in healthy older dogs has been abandoned — ageing dogs lose muscle, and protein helps preserve it. Restriction is for diagnosed kidney disease, at a level your vet sets
• Weigh monthly and record it. Drift is invisible day to day
• Check body condition, including muscle over the spine and hindquarters, which is where loss shows first

What not to do

• Do not leave food down all day. It goes stale, becomes less appealing, and you lose the ability to monitor intake
• Do not keep escalating to something tastier each meal
• Do not assume fussiness in a dog over about seven without a check-up
• Do not force-feed without veterinary guidance
• Do not withhold food to “make them hungry” in an older dog. That is a strategy for a healthy adult, not a senior who may be unwell

The thing worth remembering

In a young healthy dog, refusing food is usually a negotiation.

In an older dog, it is usually information.

Treat it as information first, get the mouth and the bloods checked, and then — once you know nothing is wrong — the practical measures above will do the rest.
