When to rush your pet to a vet: signs you should never wait on

By the Pawspert team · Updated 2026-10-09 · 7 min read · How we write our guides

Most worrying symptoms can wait until morning. A small number cannot, and the difference is often measured in hours. These are the ones where waiting costs lives.

The short answerGo to a vet immediately for difficulty breathing, seizures, collapse, suspected poisoning, a swollen belly with retching, heavy bleeding, or straining without passing urine. Pale, white, blue, muddy brown or brick-red gums are also an emergency. Not eating on its own for less than a day can usually wait for a call to your vet. Call sooner for a puppy, kitten or diabetic pet, and do not let a cat go more than a day or two without food, as it risks fatal fatty liver disease.

Go now, without waiting

These do not improve on their own, and the window for treating them is short.

SignWhat it may mean
Difficulty breathing, open-mouth breathing in a catAirway obstruction, fluid on the lungs, heart failure
Seizure, or several close togetherA seizure lasting over five minutes, or repeated seizures, can cause brain damage and dangerous overheating
Sudden collapse or inability to standInternal bleeding, cardiac event, severe pain
Swollen, hard abdomen with retchingBloat / GDV, see below
Straining to urinate with nothing passingUrinary blockage, can be fatal within two to three days, sometimes sooner
Suspected poisoningChocolate, xylitol, rodenticide, paracetamol, lilies for cats
Uncontrolled bleedingApply pressure and travel
Pale, white, blue, muddy brown or brick-red gumsBlood loss, shock, oxygen failure
Hit by a vehicle, even if walkingInternal injury is frequently invisible for hours
Repeated vomiting with lethargyObstruction, pancreatitis, toxicity
Two or more signs togetherWhen several appear at once, the risk of something serious rises sharply. Do not wait to see whether they settle.

Bloat, explained properly

Gastric dilatation-volvulus deserves its own section because it is fast, common in deep-chested breeds, and frequently misread as an upset stomach.

The stomach fills with gas and rotates on itself, sealing both ends and cutting off its own blood supply. Untreated it can kill within hours. The signature sign is retching that produces nothing, the dog is clearly trying to vomit and nothing comes up, because nothing can. Add a hard, swollen belly, restlessness and drooling, and you should already be travelling.

Great Danes, German Shepherds, Weimaraners, Irish Setters, St Bernards and Standard Poodles carry higher risk. Risk is higher in dogs fed one large meal a day, older dogs and deep-chested breeds, so vets advise smaller meals and rest around mealtimes.

The cat emergency people miss

A male cat straining in the litter tray is not constipated until proven otherwise. Urethral obstruction is common in male cats, blocks urine entirely, and can kill within about three days, sometimes sooner, as toxins and potassium build up in the blood.

The reason it gets missed is that it looks like constipation, repeated trips to the tray, straining, crying, nothing produced. If you see this in a male cat, treat it as an emergency tonight.

What can reasonably wait

Equally useful to know, so you are not in an emergency clinic at 2am unnecessarily:

These are ideal candidates for a next-morning appointment or a video consult, which is precisely what remote consultation is good for. Our guide to online vet consultation in India covers what a vet can and cannot assess remotely.

Before it happens

Emergencies are won on preparation, at 2am, when you are not thinking clearly.

  1. Know your nearest 24-hour clinic now. Not when you need it. Save the number and check they are genuinely staffed overnight.
  2. Keep an emergency fund. ₹20,000–₹30,000 covers most crises; major surgery can exceed ₹50,000.
  3. Have the medical history reachable. An emergency vet meeting your pet for the first time works better knowing the vaccination status, medications and prior conditions.
  4. Know your pet's normal. Gum colour, resting breathing rate, usual energy. You cannot spot a change from baseline without knowing the baseline.
Why records matter at 2amThe emergency vet has never met your animal. Whether they can see the vaccination history, current medications and past diagnoses in ten seconds genuinely changes the speed and safety of what happens next. Pawspert keeps that behind a QR code any vet can scan, without needing an account.

This guide is general information, not veterinary advice. If you are worried about your animal right now, contact a vet rather than reading further.

Frequently asked questions

What counts as a veterinary emergency?

Difficulty breathing, seizures, sudden collapse, suspected poisoning, severe trauma, uncontrolled bleeding, inability to urinate, and a bloated or distended abdomen. Any of these mean go to a clinic immediately rather than waiting or booking a remote consult.

My dog is not eating. Is that an emergency?

Not on its own. Not eating for more than 24 hours warrants contacting your vet. It becomes urgent when combined with other signs, repeated vomiting, lethargy, a swollen abdomen or pale gums. Multiple symptoms together raise the risk considerably.

What is bloat in dogs?

Gastric dilatation-volvulus, or GDV. The stomach fills with gas and twists, cutting off its own blood supply. It can be fatal within hours and is a surgical emergency. Signs are a swollen abdomen, restlessness, drooling, and repeated unproductive attempts to vomit, retching with nothing coming up.

Can I use an online vet consultation in an emergency?

No. Telemedicine is for triage and non-urgent questions. In a genuine emergency the time spent on a video call is time not spent travelling to a clinic that can provide oxygen, fluids and surgery.

How do I check my pet's gums?

Lift the lip and look. Healthy gums are pink and moist. Press gently until the spot blanches white and release, colour should return within about two seconds. Pale, white, blue, muddy brown or brick-red gums, or a slow refill, all warrant immediate attention.

Kutte ko fever ho to kya kare?

Pehle thermometer se temperature naapein; kutte ka normal lagbhag 37.5 se 39.2 degree Celsius hota hai. Paani dein aur thandi jagah rakhein, lekin paracetamol jaisi insaan ki dawai na dein. Bukhar ke saath susti ya khana na khana ho to vet ko dikhayein, kyunki yeh tick fever ho sakta hai.
