Signs Your Dog or Cat Needs a Vet Today
In this guide
Pets cannot tell us when something is wrong, and many — cats especially — instinctively hide pain and illness. By the time a problem is obvious, it may already be serious.
Knowing which signs are genuine emergencies helps you act quickly when it matters, and avoid worrying unnecessarily when it does not. When in doubt, always phone your vet: they would much rather hear from you early.
Call a vet immediately
Contact your vet or an emergency clinic straight away if your pet shows any of these:
- Difficulty breathing, choking, or blue or very pale gums
- Collapse, seizures, or sudden weakness
- A swollen, hard belly with retching that brings nothing up (a sign of bloat in dogs)
- Straining to urinate with little or no urine — especially urgent in male cats
- Suspected poisoning, even if your pet seems fine
- Heavy bleeding, major injuries, or being hit by a car
- Signs of heatstroke: heavy panting, drooling, confusion
See a vet within a day
These problems need prompt attention, usually the same or next day:
- Vomiting or diarrhoea lasting more than a day, or containing blood
- Not eating for more than a day (cats) or two days (dogs)
- Limping that does not improve within a day
- Eye injuries, squinting, or a cloudy eye
- Sudden changes in drinking or urination
Book a routine appointment
Gradual changes are still worth checking, even if they are not urgent: slow weight gain or loss, bad breath, lumps and bumps, reduced activity, and changes in coat quality. Many diseases are easier to treat when caught early.
Why cats are tricky
Cats are experts at hiding illness. Subtle changes — hiding more, grooming less, sitting hunched, or using the litter box differently — may be the only warning signs. Trust your instincts; you know your cat's normal behaviour best.
Be prepared
Save your vet's phone number and the nearest out-of-hours emergency clinic in your phone. Keep a note of your pet's medicines, weight, and medical history, and know how you would get there quickly at night.
This is general pet-care information, not veterinary advice. Every animal is different — if you are worried about your pet's health or behaviour, contact your veterinarian. In an emergency or a suspected poisoning, call your vet or an animal poison-control line immediately.
