Signs your pet needs a vet now

Updated By PetymFacts checked against official sources on

Quick answer

Go to a vet now if your pet is struggling to breathe or has white, blue or grey gums, collapses, has a seizure lasting over two minutes, retches without bringing anything up with a swollen belly, is a cat straining to pee with nothing coming out, may have eaten poison, is bleeding heavily, or was hit by a vehicle.

If you are not sure, call your vet or the nearest 24-hour vet and describe what you see. The 2026 RECOVER first-aid guidelines say that almost every worrying sign should lead to the nearest open vet clinic. Calling ahead lets the clinic prepare for your arrival.

Which signs mean go to a vet now?

Any one of these is an emergency. Do not wait until morning, and do not wait to see if it passes.

Should you go now, call today or watch at home?

A rough sort, not a diagnosis. When in doubt, call: the vet would rather hear from you early.

  1. If Any sign on the list above

    Go now. Phone the vet or the nearest 24-hour vet on the way so they can prepare. Emergency vets PDSA

  2. If Vomiting that keeps going, a dog that does not seem right after 24 hours, or gets worse at any point

    Call your vet the same day. PDSA

  3. If Bloody diarrhoea, or diarrhoea lasting more than two to three days

    Call your vet the same day. PDSA

  4. If An adult cat that has not eaten for a day

    Call your vet. Cornell says loss of appetite can harm a mature cat's health in as little as 24 hours; in a kitten under six weeks, 12 hours can be dangerous. Cornell Feline Health Center

  5. If A dog with a hacking cough after boarding or day care, otherwise bright and eating

    Call your vet for advice and keep the dog away from other dogs. Go sooner if it stops eating or is lethargic. PDSA

  6. If A single short episode of loose stool with no blood, in a dog that is otherwise well

    Home care can be reasonable. Call if it lasts more than a few days or anything else changes. PDSA

Why is a cat straining to pee an emergency?

Because a blocked bladder can kill a cat within a day or two.

Cornell's Feline Health Center calls urethral obstruction a true medical emergency that needs immediate veterinary attention. A blocked cat strains, keeps trying to urinate and produces little if any urine, and becomes more and more distressed, often crying in pain. Male and neutered male cats are at greater risk. Cornell warns that the time from a complete blockage to death may be less than 24 to 48 hours.

PDSA's advice is not to watch and wait to see whether the symptoms improve. Owners often mistake straining for constipation, because the cat squats in the tray and nothing seems to happen. If a cat, especially a male, is going in and out of the litter tray and passing nothing, go to a vet now.

What does bloat look like in a dog?

Repeated dry retching, a swollen belly and a restless, uncomfortable dog.

Bloat, or gastric dilatation and volvulus, is when the stomach fills with gas and can twist. The Merck Veterinary Manual describes it as a life-threatening emergency that mainly affects large, deep-chested dogs, and names the Dobermann, German Shepherd, Great Dane and Saint Bernard among the breeds most often affected. Signs include restlessness, apparent discomfort, fast breathing, a painful, swollen belly, repeated dry retching and drooling.

Merck advises seeking veterinary care immediately, because prompt treatment improves the chance of survival. PDSA also lists continuous retching with a bloated tummy as a life-threatening emergency. Do not wait to see if your dog passes wind or settles.

How do emergency signs differ in dogs and cats?

Cats hide illness well, so in a cat a small change can mean a big problem.

In a dogIn a cat
Breathing PDSANoisy, fast or laboured breathing; stretching the neck out.Any open-mouth breathing or panting at rest is serious.
Not eating Cornell Feline Health CenterRefusing food for more than a day, especially with vomiting, needs a vet visit.A day without food can harm an adult cat's health; 12 hours can be dangerous for a kitten under six weeks.
Toilet trouble Cornell Feline Health CenterStraining to pass stool for more than a day needs a vet.Straining to pee and passing little or nothing is an emergency, most of all in males.
Poison most often met US Food and Drug AdministrationChocolate, grapes and raisins, onion and garlic food, xylitol.Lilies, including pollen and vase water, and human medicines such as paracetamol.
Hidden pain or distress International Cat CareA painful belly can make a dog hunch or lower its front end; restlessness and not settling are warnings too.Hiding, eating less or more than normal, over-grooming and soiling outside the tray can all signal stress or illness.

How do you get to a vet at night in an Indian city?

Plan it before you need it. In an emergency, minutes go on finding a number and a car.

These are Petym's practical steps. The clinical rule behind them is the RECOVER guidelines' advice to go to the nearest open veterinary clinic as soon as possible after first aid.

  • Save your own vet and the nearest 24-hour vet in your phone today. Petym's vets directory lists 24-hour vets we have checked, city by city.
  • Call ahead on the way. PDSA advises ringing so the clinic can prepare for an emergency case.
  • Know how you will travel: your own car, a neighbour with a car, or a cab or auto that will take a pet. Not every driver will, so have a second option.
  • Keep a carrier for a cat or small dog by the door, and a blanket that can be used as a stretcher for a big dog.
  • In a housing society, tell the guard you are leaving in a hurry so the gate and lift are not a delay.
  • Take your pet's vaccination card, any medicines it takes and, for a poisoning, the packet or plant.

Why should a pet that seems fine after an accident still see a vet?

Because some of the most serious injuries do not show at first. The Merck Veterinary Manual lists severe pain, uncontrolled bleeding, breathing trouble, eye injuries, suspected broken bones and poisoning as emergencies needing immediate care. A dog that walks away from a scooter can still be bleeding inside, and a cat that falls from a balcony can have chest injuries that only show as faster breathing later.

The 2026 RECOVER guidelines put it simply: every animal that needs first aid should be seen by a vet as soon as possible. If you are in two minds, phone the vet and describe what happened. Let them decide whether it can wait.

What about snakebites and the monsoon?

Pets meet snakes in long grass, overgrown gardens and construction sites, and many Indian monsoon walks pass all three. The Merck Veterinary Manual calls a venomous snakebite a true emergency and says owners should not spend time on first aid beyond keeping the animal quiet and limiting its activity. Cutting the wound, suction, ice, tourniquets and electric shock do not work and can harm.

Merck also notes that with cobra-family bites, pain and swelling are usually minimal, so a lack of swelling does not mean a bite was harmless. If you saw a snake near your pet, or your pet yelped and is now weak, drooling or wobbly, go to a vet now. Take a photo of the snake only if you can do it from a safe distance.

What does a Petym sitter do if they see these signs?

Every Petym sitter completes pet first-aid training before their first booking and has a named 24-hour vet within reach. If a sitter sees an emergency sign, the sitter will call you and take your pet to the nearest 24-hour vet on the city's list. The daily photo update and the pet's plan, logged as it happens, help a sitter notice when something has changed.

Before you travel, add your vet, the nearest 24-hour vet and any known health conditions to your pet's care sheet, and say how the sitter can reach you at any hour.

Questions owners ask

How do I know if my dog needs an emergency vet?

Go now if your dog is struggling to breathe, has white, blue or grey gums, collapses, has a seizure over two minutes, retches without bringing anything up with a swollen belly, may have eaten poison, is bleeding heavily or was hit by a vehicle. If unsure, call your vet or the nearest 24-hour vet.

Is a cat straining in the litter tray an emergency?

It can be. A cat straining to pee and passing little or nothing may have a blocked bladder. Cornell's Feline Health Center warns that a complete blockage can kill within 24 to 48 hours, and male cats are at greater risk. Go to a vet now; do not wait to see if it passes.

What are the signs of bloat in dogs?

Repeated dry retching that brings nothing up, a swollen, painful belly, restlessness, fast breathing and drooling. The Merck Veterinary Manual says bloat mainly affects large, deep-chested dogs such as the Great Dane, German Shepherd and Dobermann, and is a life-threatening emergency needing a vet immediately.

How long can a cat go without eating?

Not long. Cornell's Feline Health Center says loss of appetite can severely affect a mature cat's health if it lasts as little as 24 hours, and for a kitten under six weeks, 12 hours can be life-threatening. Call your vet if your cat stops eating, rather than waiting several days.

When is a seizure an emergency?

PDSA advises calling your vet straight away if a seizure lasts more than two minutes or your pet has more than one seizure in 24 hours. Cornell says go to a clinic immediately if a dog has been seizing for more than five minutes. After any first seizure, book a vet check once your pet recovers.

Should I take my dog to the vet after a minor accident if it seems fine?

Yes. The Merck Veterinary Manual lists road accidents, falls and suspected fractures among emergencies, and some injuries, such as internal bleeding or chest damage, do not show at first. The 2026 RECOVER guidelines say every animal that needed first aid should be seen by a vet as soon as possible.

Where can I find a 24-hour vet in India?

Ask your own vet which emergency clinic they use out of hours, and save its number now. Petym's vets directory lists 24-hour vets it has checked city by city, with the source for each. Call ahead on the way so the clinic can prepare for an emergency case.

What gum colour means an emergency?

Healthy gums are usually pink. PDSA lists white, blue or grey gums as a sign of a breathing emergency: go to the nearest vet immediately and phone ahead. Look at your pet's gums when it is well, so that a change is easier to spot in an emergency.
