As a loving pet owner, it’s natural to notice every wag, purr or peculiar habit. But when should you start to worry that something’s not quite right? Pets can’t tell us when they’re feeling off – so it’s up to us to spot the signs of ill health early.

1. Changes in appetite or drinking habits

If your pet suddenly eats much less (or more) than usual, or is drinking excessively, it could signal anything from dental disease to diabetes or kidney problems.

2. Behavioural changes

Has your usually affectionate cat become withdrawn? Is your lively Labrador suddenly lethargic? Changes in mood, activity or interaction can be early indicators of pain or discomfort.

3. Vomiting or diarrhoea

Occasional tummy upsets aren’t unusual, but ongoing vomiting or diarrhoea can indicate infection, parasites, allergies, or something more serious.

4. Breathing issues

Wheezing, persistent coughing or laboured breathing should never be ignored. These symptoms could suggest anything from a respiratory infection to heart disease.

5. Poor coat condition or itching

A healthy pet’s coat should be glossy and smooth. Flaky skin, bald patches, or frequent scratching might mean allergies, parasites, or hormonal imbalances.

6. Changes in weight

Sudden weight gain or loss can be subtle but important. Regular weigh-ins can help catch long-term health issues early.

7. Lumps, bumps and swellings

While not all lumps are dangerous, any new growth or swelling should be checked by a vet – especially if it’s growing or painful.

8. Bad breath or dental problems

Dental disease is one of the most common conditions seen in UK pets. If your pet has smelly breath, is drooling more than usual or struggling to chew, book a check-up.
