Off their food
One skipped meal in an otherwise bright dog is common. Ring your vet if it's more than about 24 hours, if a puppy skips meals, or if there's vomiting, lethargy or a swollen belly alongside it.
My Dog
Something seems different?
A calm place to work out whether this is a wait-and-see, or a ring-the-vet.
This is general information, not a diagnosis. Some changes are harmless and some aren't, and the difference often isn't obvious from the outside.
If you're worried, or the change came on suddenly or severely, contact your vet. Worry on its own is a good enough reason to call.
Drinking a lot more or less
A clear change that lasts more than a couple of days is worth investigating rather than watching. Take a note of roughly how much.
Vomiting
One vomit, then back to normal, often settles. Call if it's repeated, if they can't keep water down, if there's blood, if they're trying to be sick without producing anything, or if they may have swallowed something.
Diarrhoea
Mild and short-lived is common. Call if it lasts beyond a day or two, contains blood, or comes with vomiting, pain or a flat, tired dog — and sooner for puppies and older dogs, who dehydrate quickly.
Coughing
An occasional cough after pulling on a lead is different from a cough that keeps going. Persistent coughing, coughing at night, or any breathing difficulty needs a vet.
Itching
Constant scratching, licking or chewing is uncomfortable and usually has a cause worth finding — parasites, skin infection or allergy. It rarely resolves with shampoo alone.
Limping
Mild limping that settles within a day with rest can be watched. Non-weight-bearing lameness, obvious pain, swelling or a limp that lasts should be seen.
Unusual tiredness
A quiet day happens. A dog who won't get up, is unsteady, or is much flatter than usual should be seen promptly.
