Knowing when to take your dog to the emergency vet comes down to a short list: trouble breathing, bleeding that won't stop, a possible poisoning, severe pain, an eye injury, a leg your dog won't use, collapse, or a swollen belly with retching that brings nothing up. If you see any of these, call your vet or the nearest emergency animal hospital and go now.
Everything else sits in a grey zone, and honestly, a phone call is what settles it. Below are the signs that official veterinary sources treat as emergencies, the ones that can usually wait for your clinic to open, and how to get your dog there in one piece. This isn't veterinary advice. If you're unsure, call a vet.
When to take your dog to the emergency vet right away
Go right away for poisoning, severe pain, uncontrolled bleeding, trouble breathing, eye injuries, or a suspected broken bone or limb that can't move. Those come straight from the Merck Veterinary Manual's guide for pet owners, which also lists unconsciousness, choking, burns, heatstroke, hypothermia and strangulation injuries, like a collar that's caught on something.
| What you see | Why it can't wait |
|---|---|
| Struggling to breathe, blue or very pale gums, choking | Breathing problems can kill within minutes |
| Bleeding that soaks through pressure and a bandage | Severe or uncontrolled bleeding is on Merck's emergency list |
| Ate something toxic, or you think so | Poisoning is an emergency even before any signs show up |
| Swollen belly, retching with nothing coming up, drooling, restlessness | These are signs of bloat (GDV), which is life threatening |
| Collapse, unconsciousness, seizures that don't stop | A vet needs to check airway, breathing and circulation |
| Hot skin, heavy panting, drooling, stumbling after heat | Signs of heatstroke, which needs a vet right away |
| Injured eye, or a leg your dog won't put down | Both are on Merck's list of immediate emergencies |
| Hit by a car, a fall, a fight, or any big trauma | Injuries can be internal even when your dog seems fine |
If your dog can't breathe properly, won't stop bleeding, has collapsed or may have eaten something toxic, call ahead and go to a vet or emergency clinic now.
Bloat: the emergency big dogs are prone to
Bloat is when the stomach fills with gas and can twist, and it needs surgery fast. Vets call it gastric dilation and volvulus, or GDV. The Merck Veterinary Manual describes it as acute and life threatening, needing immediate medical and surgical treatment, and it notes that delay raises the risk of death.
Picture a big dog pacing the kitchen after dinner, trying to throw up and getting nothing, drooling, and looking rounder through the middle than it did an hour ago. That's the pattern to know. Later signs include collapse, pale gums and laboured breathing.
Large and giant breeds with deep, narrow chests are most at risk. Merck names Great Danes, German Shepherds, Standard Poodles, Weimaraners, Saint Bernards, Irish and Gordon Setters, and Basset Hounds. If you share your home with one of them, it's worth knowing these signs by heart.
Don't wait and see with bloat. Go to an emergency clinic straight away, whatever the hour.
If your dog ate something it should not have
Call your vet, an emergency clinic or a pet poison line right away, even if your dog looks completely normal. Poisoning is on every emergency list, and the earlier you act, the more options the vet has. Skip the home remedies, and don't make your dog vomit unless a vet tells you to.
The ASPCA Animal Poison Control Center answers at (888) 426-4435, 24 hours a day, 365 days a year. A consultation fee may apply. Before you dial, grab the package or snap a photo of what your dog got into, and have a rough amount, the time it happened and your dog's weight ready.
Urgent vet or wait: what can usually wait for a call
Some problems can often wait for your own clinic to open, as long as your dog is otherwise bright, eating and drinking. Notice the word often. If something's getting worse, or you just aren't sure, call.
- One bout of vomiting or loose stool in a dog that's otherwise acting normal
- A mild limp where your dog still uses the leg
- Itchy skin, a small scrape, or a minor ear problem
- Skipping one meal with no other signs
- A lump you've just noticed, with no pain or bleeding
Any of those can turn urgent. It changes when the sign keeps coming back, when your dog is a puppy or a senior, or when it comes with weakness, pain, a swollen belly or refusing water. Many emergency hospitals will tell you on the phone whether to come in. That call is never wasted.
What to do before and on the way
Start with a phone call to the clinic you're heading to. Merck's guide says emergency care often begins there: the team can tell you how to move your dog, and they can get ready before you walk in.
- Keep yourself safe, because a dog in pain may bite. Merck says a soft muzzle can help, but never muzzle a dog with chest injuries or trouble breathing, a short-nosed breed, or a dog that will be left alone.
- Stop bleeding with firm pressure from a clean cloth, then bandage it snugly but not too tight. If blood soaks through, add more on top instead of pulling the first layer off.
- Move an injured dog gently, keeping the head, neck and back as still as you can on a firm board, thick cardboard or a folded blanket.
- Cool an overheated dog by getting it out of the heat and wetting it with cool water, not ice cold, then drive straight to the vet.
- Bring anything that helps the team: packaging from a suspected poison, your dog's medicines, and its vaccine and health history.
That last one is a lot easier if the records are already on your phone. The free PetGrid app keeps your pet's records and vaccine card in one place, so you can show an emergency vet the history at 2 a.m. without trying to reach your regular clinic.
Find your nearest emergency clinic before you need it
Look up your emergency hospital now, on a calm afternoon, not in the middle of a crisis. Ask your clinic which after-hours hospital it works with, save the number in your phone, and check how long the drive actually takes at night. In the PetGrid app, the find a vet map shows every vet clinic, not only the ones on PetGrid, and you can browse vets in Toronto and other cities on the web.
While you're at it, pack a kit. Our pet emergency kit checklist goes through what to put in it, from gauze and a soft muzzle to copies of your records.
Questions people ask
How do I know if my dog needs the emergency vet?
Go now if your dog has trouble breathing, bleeding that won't stop, a possible poisoning, severe pain, an eye injury, a leg it can't use, has collapsed, or has a swollen belly with retching that brings nothing up. If you're unsure, phone an emergency clinic and describe what you see. They'll tell you whether to come in.
Is vomiting an emergency for a dog?
One bout of vomiting in a dog that's otherwise bright often isn't an emergency, but call your vet. Repeated vomiting, vomiting with weakness or a swollen belly, retching with nothing coming up, or vomiting after eating something toxic means go to a vet now.
What are the signs of bloat in dogs?
The main signs are retching that brings nothing up, heavy drooling, restlessness and a belly that's swelling. The Merck Veterinary Manual calls bloat (GDV) life threatening and says it needs immediate treatment, so head to an emergency clinic straight away.
Who do I call if my dog ate something poisonous?
Call your vet, an emergency animal hospital or a pet poison line right away. The ASPCA Animal Poison Control Center answers at (888) 426-4435 every day of the year, and a fee may apply.
Should I call before going to the emergency vet?
Yes, if you can do it without losing time. The team can tell you how to move your dog safely and get ready for you. But if your dog can't breathe, don't let the call hold you up.
What should I bring to an emergency vet visit?
Bring your dog's medicines, any packaging from what it ate, and its vaccine and health history. If those records live on your phone, you'll have them even when your regular clinic is closed.
