If you're reading this in an emergency
Phone your vet's number now. Most UK practices either provide their own out-of-hours cover or refer to a dedicated emergency centre. The recorded message or live operator will tell you where to go. Try to call before driving — the emergency provider may not be the nearest building, and they may need to prepare for your arrival.
What counts as an emergency
A pet emergency is generally anything that threatens life, causes severe pain, or risks rapid deterioration if untreated. The hard part is recognising it in real time, often when you're tired, stressed, or trying to convince yourself it's not as bad as it looks.
The red-flag symptoms below are drawn from UK veterinary guidance from groups like Blue Cross, PDSA, RSPCA, and emergency veterinary hospitals. When in doubt, call. Phone triage is generally free, and a qualified nurse or vet on the line tends to be far better than guessing.
Red-flag symptoms — call now
| System | What to look for | Why it's urgent |
|---|---|---|
| Breathing | Open-mouth breathing in cats; resting respiratory rate over 40 breaths per minute in dogs; blue or pale gums; noisy wheeze or panting that won't settle. | Respiratory distress can develop quickly. Cats rarely breathe through an open mouth unless something is seriously wrong. |
| Bloat (dogs) | Distended, hard abdomen; pacing or restlessness; drooling; unproductive retching (trying to vomit but bringing nothing up). | Gastric Dilatation-Volvulus (GDV) can be fatal within hours, particularly in deep-chested breeds. Treat as urgent. |
| Seizures | Any seizure lasting longer than 3 minutes; multiple seizures in a short window; not regaining consciousness between fits. | Status epilepticus risks brain damage. Single short seizures still warrant same-day vet review but generally aren't quite as time-critical. |
| Collapse | Sudden weakness; unable to stand; pale gums; weak or rapid pulse. | Often signals internal bleeding, severe dehydration, or cardiac issues. |
| Trauma | Hit by a car; fall from height; serious bite wound; even if your pet seems fine afterwards. | Internal injuries can be invisible. It's worth getting them checked, even if the animal walks away. |
| Suspected poisoning | Known ingestion of chocolate, grapes/raisins, xylitol (sweetener), antifreeze, lily plants (cats), human medication, or rodenticide. | Many pet poisons have a treatment window of hours. Take packaging or photo of the substance with you. |
| Unable to urinate | Straining unsuccessfully; crying; obvious pain. More common in male cats. | A blocked bladder can be fatal within 24–48 hours. Particularly urgent in cats. |
| Severe bleeding | Blood that won't stop with three minutes of firm pressure; coughing up blood; bloody urine; bleeding gums or rectum. | Severe blood loss, internal bleeding, or clotting disorders generally need urgent intervention. |
| Eye trauma or sudden blindness | Red, painful eye; cloudy eye that wasn't cloudy yesterday; pet won't open the eye; sudden inability to see. | Vision can be lost permanently within hours in some conditions. Eye emergencies are typically treated as urgent. |
Cats often hide emergencies better than dogs
A cat that seems quiet and is hiding under the bed may not be just resting. In feline medicine, withdrawal from normal behaviour is itself a useful warning sign — cats often mask pain instinctively. If a cat suddenly stops eating, hides, or refuses to move, it's generally worth treating as a medical concern, not a mood.
What to do before you leave
- Call first. Your day practice's number is generally the right one to ring even at 3am. The recorded message or staff on call will route you correctly.
- Get the address ready. Save the emergency provider's address in your phone tonight, before you ever need it.
- Bring information. Any packaging from a suspected poisoning, a list of current medications, your pet's vaccination card if accessible.
- Stabilise without making things worse. Apply pressure to bleeding wounds. Keep your pet warm and quiet. Don't give food, water, or human medicines unless told to.
- Drive safely. Tempting to speed; better to arrive than not. Bring someone if you can — one to drive, one to comfort the pet.

What about the 24/7 advice lines?
Several UK pet insurers and charities run telephone triage lines (Vetfone, PDSA, Blue Cross). They can help you decide whether to drive in or wait until morning, but they generally aren't a replacement for an emergency vet when symptoms match the red-flag list. Your insurer's policy may also cover the consultation — worth knowing the answer before the bill arrives.

Most pet owners only learn their out-of-hours route during the emergency itself. Five minutes spent now — saving the number, the address, and your insurance details — is among the cheapest insurance you'll buy. The signs above will help you recognise when to dial.
