My dog isn't eating — what should I do?
A dog going off its food can be minor — a hot day, a reaction to a new food, or fussiness — or a sign of something serious. The key is knowing how long to watch and when to treat it as urgent. This is general guidance, not a diagnosis; when in doubt, call your vet.
Common, less-serious reasons
Dogs may eat less in peak summer heat, after vaccination, when stressed (travel, a new home, fireworks), or simply because they've been given too many treats or table scraps. A single skipped meal in an otherwise bright, active dog is usually not an emergency — offer fresh food, cut out treats, and see if appetite returns within a day.
When it's a red flag
Treat it as urgent — and see a vet promptly — if your dog also has vomiting or diarrhoea, lethargy, a bloated or painful belly, pale gums, is trying to vomit without success, hasn't eaten for more than about 24 hours, or is a puppy or senior (they can decline fast). Refusing food plus any of these signs needs veterinary attention, not waiting.
What you can safely do meanwhile
Make sure fresh water is available, remove uneaten food after 20 minutes so it doesn't spoil in the heat, and try a small amount of plain boiled chicken and rice to tempt a fussy but otherwise-well dog. Don't give human medicines or force food. If appetite doesn't bounce back quickly, or any red flag appears, contact your vet.
Frequently asked questions
How long can a dog go without eating before I worry?
A healthy adult dog skipping one meal is usually fine, but loss of appetite beyond about 24 hours — or any time it comes with vomiting, lethargy or other symptoms — needs a vet. Puppies and seniors should be seen sooner.
Why is my dog not eating but acting normal?
It could be heat, mild fussiness, stress, or too many treats. Offer fresh food, stop the treats, and monitor. If it continues beyond a day or other signs appear, see a vet.
Is loss of appetite an emergency?
It can be, especially with vomiting, diarrhoea, lethargy, a painful belly or pale gums, or in puppies and seniors. When in doubt, contact your vet — don't wait it out.
