If your pet is showing any of these symptoms, don’t wait for your regular vet to open. Head to an emergency veterinary clinic immediately.
Laboured breathing, wheezing, gasping, or blue-tinged gums mean your pet isn’t getting enough oxygen. This can be caused by an obstruction, allergic reaction, pneumonia, or heart failure. Every minute without adequate oxygen risks brain damage and cardiac arrest.
A seizure looks like uncontrollable shaking, paddling legs, drooling, or loss of consciousness. A single seizure lasting more than 2–3 minutes, or multiple seizures in a row (cluster seizures), is a medical emergency. Prolonged seizures can cause permanent brain damage and dangerously high body temperature.
Common household toxins include chocolate, xylitol (found in sugar-free gum and peanut butter), antifreeze, rat poison, grapes/raisins, and lilies (extremely toxic to cats — even the pollen). Symptoms include vomiting, tremors, excessive drooling, sudden lethargy, or loss of coordination.
A hard, swollen belly — especially in large, deep-chested dogs like Great Danes, German Shepherds, or Standard Poodles — can signal gastric dilatation-volvulus (GDV or bloat). The stomach fills with gas and twists on itself, cutting off blood supply to vital organs. Without emergency surgery, GDV is fatal within hours.
If your pet is straining in the litter box or outside and producing little or no urine, this is urgent — especially in male cats. A urinary blockage prevents waste from leaving the body, causing toxins to build up in the bloodstream. A blocked male cat can develop fatal kidney failure or a ruptured bladder within 24–48 hours.
Any wound that exposes muscle, bone, or deeper tissue — or bleeding that doesn’t slow after 5 minutes of firm pressure — needs emergency veterinary care. Even if bleeding eventually slows, internal damage or infection risk makes professional assessment essential.
Even if your pet walks away from being hit by a vehicle, internal injuries like organ damage, internal bleeding, or fractures may not be immediately obvious. Adrenaline can mask pain for hours. Any significant trauma — falls from height, being kicked, or crush injuries — warrants an immediate vet visit.
If your pet suddenly can’t stand, collapses mid-walk, or goes limp, this can indicate heart failure, internal bleeding, a spinal injury, or a severe metabolic problem. Carry your pet to the car (don’t let them walk) and get to the nearest emergency clinic. For large dogs, use a blanket as a stretcher to avoid worsening a spinal injury.
A single episode of vomiting is usually nothing to panic about. But vomiting or diarrhea that continues for more than 24 hours, contains blood, or is accompanied by lethargy and refusal to eat signals something serious — from an intestinal obstruction to pancreatitis to parvovirus. Dehydration can become dangerous quickly, especially in puppies, kittens, and small-breed dogs.
A scratched cornea, a puncture wound, sudden swelling, or your pet bumping into things they normally navigate easily all require urgent attention. Eye injuries deteriorate rapidly — a scratch can become an ulcer or lead to loss of the eye within days without treatment.
Heavy panting, thick drooling, bright red gums, disorientation, vomiting, or collapse in warm weather are signs of heatstroke. Heatstroke can cause organ failure, brain damage, and death within minutes if body temperature exceeds 41°C (106°F).
Pets hide pain instinctively, so visible signs mean it’s serious. Watch for whimpering or crying out, trembling, panting at rest, hiding, refusing to move, or snapping when a specific area is touched. Severe pain can indicate fractures, internal injuries, or conditions like pancreatitis that need immediate treatment. Never give human pain medication — ibuprofen and acetaminophen (Tylenol) are toxic to dogs and cats.
Dogs are notorious for swallowing bones, toys, socks, corn cobs, and string. Cats go after thread, ribbon, and hair ties. If you see your pet swallow something they shouldn’t have, or they’re suddenly gagging, drooling, or refusing food, an X-ray can determine if surgery is needed before the object causes a bowel blockage or perforation.
Lift your pet’s lip and check their gum colour. Healthy gums are pink. White or grey gums indicate internal bleeding, shock, or severe anemia. Blue or purple gums mean oxygen deprivation. Press a finger against the gum — it should return to pink within 2 seconds (capillary refill time). Longer than that means something is seriously wrong.
If your dog or cat has been actively straining for more than 30 minutes without producing a puppy or kitten, or if more than 2 hours have passed between births when you know more are coming, this is an emergency. Dystocia (difficult birth) often requires a C-section. A stuck puppy or kitten can endanger the entire litter and the mother’s life.
Emergency vet visits can cost $150–$5,000+ depending on severity, but early treatment almost always costs less than waiting until a condition becomes critical. Use our vet cost calculator to estimate what you might pay.
Not every scary symptom is a true emergency. Here are situations where you can usually monitor at home and see your regular vet the next morning:
If your pet is putting some weight on the leg, isn’t crying in pain, and the limb isn’t at an odd angle, rest overnight and monitor. Restrict activity and see your vet the next day. If they won’t bear any weight at all, go in.
One vomit, especially after eating grass or eating too fast, is usually not an emergency. Withhold food for a few hours, then offer a small bland meal. If vomiting continues, if there’s blood, or if your pet becomes lethargic, that changes things.
Clean with lukewarm water, apply gentle pressure if bleeding, and keep the area clean. If the wound is shallow and your pet is acting normally, your regular vet can check it during business hours.
Dogs and cats occasionally skip a meal for no serious reason. If your pet is otherwise alert, drinking water, and acting normal, missing one meal isn’t cause for an emergency visit. Two or more missed meals in a row, especially in cats, warrants a vet call.
A single episode of soft stool or mild diarrhea — without blood, without vomiting, and with a pet that’s still active and drinking — can usually wait. Offer a bland diet (boiled chicken and rice) and see your vet if it continues past 24 hours.
When you’ve decided it’s an emergency, these steps can make the visit smoother and improve your pet’s outcome:
Dogs and cats don’t show emergencies the same way. Recognizing the differences can help you act faster.
A cat in severe pain may simply become quiet, stop eating, and hide under the bed. They rarely cry out the way dogs do. If your normally social cat suddenly becomes withdrawn and stops grooming, take it seriously — by the time a cat shows obvious signs of distress, the problem is often advanced.
Male cats have a narrow urethra that’s prone to blockage from crystals or mucus plugs. A blocked male cat can die within 24–48 hours. Frequent trips to the litter box, crying while urinating, or licking at the genitals are red flags that demand same-day veterinary care.
GDV (bloat) almost exclusively affects dogs, particularly deep-chested breeds. Dogs also tend to eat things they shouldn’t more readily than cats — chocolate, socks, corn cobs, and xylitol gum are all classic dog emergencies. Cats, on the other hand, are more vulnerable to lily toxicity (even the pollen can cause kidney failure) and string-type foreign bodies.
