Dog symptom checker: emergency triage guide
Use this triage guide to sort your dog's symptoms into three buckets: emergency (go to an ER now), same-day (call your vet today), or monitor at home for 24-48 hours. Go immediately for difficulty breathing, collapse, a bloated hard belly with unproductive retching, seizures lasting over two minutes, suspected poisoning, uncontrolled bleeding, or straining to urinate without producing urine. Anything painful, rapidly worsening, or lasting more than 48 hours needs a vet the same week - when in doubt, scan and call.
This page is general pet health information, not a diagnosis or treatment plan for your pet. Always confirm anything urgent with a licensed veterinarian.
When to see a vet today
See a vet today if you notice Laboured breathing, blue or grey gums, or open-mouth panting at rest, Collapse, unresponsiveness, or sudden hind-limb weakness, and Distended, hard abdomen with unproductive retching (possible GDV/bloat). These are the signs that should not wait for home care or a watch-and-see approach. If any of them appear, skip the rest of this guide and call your vet or an emergency clinic now - waiting is the risky option.
- ●Laboured breathing, blue or grey gums, or open-mouth panting at rest
- ●Collapse, unresponsiveness, or sudden hind-limb weakness
- ●Distended, hard abdomen with unproductive retching (possible GDV/bloat)
- ●Seizure lasting over two minutes, or repeated seizures in one day
- ●Known or suspected toxin: chocolate, xylitol, grapes, raisins, antifreeze, human medication
- ●Bleeding that does not stop after five minutes of firm pressure
- ●Straining to urinate with little or no urine produced
- ●Suspected heatstroke: heavy panting, bright red gums, temperature over 40C / 104F
- ●Hit by a car, a fall, or a large-dog bite wound - even if your dog seems fine
Safe to monitor at home
Milder signs are usually safe to watch for a day or two: One episode of vomiting or soft stool with normal energy and appetite, Mild limp that improves with rest and full weight-bearing within 24 hours, and Occasional scratching without broken skin, hair loss, or odour. Keep notes and photos so you can spot a trend. Anything that worsens, spreads, or comes with appetite, energy or behavior changes moves out of this category and into a vet visit.
- ●One episode of vomiting or soft stool with normal energy and appetite
- ●Mild limp that improves with rest and full weight-bearing within 24 hours
- ●Occasional scratching without broken skin, hair loss, or odour
- ●Slightly reduced appetite for one meal with normal drinking and behaviour
- ●Mild watery eye or a single sneeze episode with no discharge
What to photograph or record
Photograph or record Lift the lip and photograph the gums - colour is the fastest shock indicator, A 10-second video of your dog breathing at rest, filmed from the side, and A 10-second video of your dog walking away from and back toward the camera in good, even light. Clear, well-framed evidence is what lets a vet - or a PetSenseAI scan - judge the change instead of guessing from a description. The checklist below is the exact shot list.
- Lift the lip and photograph the gums - colour is the fastest shock indicator
- A 10-second video of your dog breathing at rest, filmed from the side
- A 10-second video of your dog walking away from and back toward the camera
- Close-up of the affected area (wound, eye, mouth, swelling) filling the frame
- Photo of any packaging your dog may have eaten, including the ingredient list
- Note the time symptoms started and your dog's current weight
Likely causes
The causes vets consider first for this presentation are respiratory distress, gdv / bloat, toxin ingestion, and urinary obstruction. Most are manageable once identified, but they look similar from the outside, which is why a photo-based triage and, when needed, an exam matter more than guesswork.
Respiratory distress
Heart failure, airway obstruction, pneumonia, or collapsing trachea. Blue-grey gums, an extended neck, or elbows held away from the body are always an emergency.
GDV / bloat
The stomach fills with gas and twists. Deep-chested breeds are at highest risk. Untreated, it is fatal within hours - unproductive retching plus a hard, swollen belly means drive now.
Toxin ingestion
Chocolate, xylitol, grapes and raisins, lilies, antifreeze, rodenticide, and human medications. Many toxins are treatable if seen before signs develop, so never wait for symptoms.
Urinary obstruction
Stones or crystals block urine flow. Repeated squatting with nothing produced causes kidney damage and dangerous potassium rises within 24 hours.
Trauma and internal bleeding
A car impact, a fall, or a bite from a larger dog can cause internal injury with a normal-looking exterior. Pale gums and a fast heart rate are the warning signs.
Heatstroke
Body temperature climbs faster than a dog can pant it off, especially in flat-faced breeds. Start active cooling with cool - not ice-cold - water while travelling to the clinic.
Safe home care
For mild cases, safe home care is check gum colour and capillary refill first: press the gum, colour should return within two seconds, count breaths per minute at rest - over 35 while sleeping is abnormal, and remove food and water if you suspect bloat or an obstruction, and do not induce vomiting unless a vet or poison line tells you to. These steps comfort and monitor; they do not treat the underlying cause. Stop home care and call a vet if anything in the urgent list above appears or the trend moves the wrong way.
- -Check gum colour and capillary refill first: press the gum, colour should return within two seconds
- -Count breaths per minute at rest - over 35 while sleeping is abnormal
- -Remove food and water if you suspect bloat or an obstruction, and do not induce vomiting unless a vet or poison line tells you to
- -Apply firm, continuous pressure with a clean cloth to any bleeding wound
- -For suspected heatstroke, use cool water on the paws, groin, and belly plus airflow while you travel
- -Save your nearest 24-hour ER number and a pet poison helpline in your phone now, before you need them
- -Scan your dog and log the timeline so the clinic gets a full history the moment you arrive

Frequently asked
How do I know if my dog's symptoms are an emergency?
Treat it as an emergency if your dog has difficulty breathing, pale or blue gums, collapse, a seizure over two minutes, a hard bloated belly with unproductive retching, uncontrolled bleeding, straining to urinate without producing urine, or any suspected poisoning. These conditions worsen within hours, so go to a 24-hour clinic immediately rather than waiting for an appointment.
Is an online dog symptom checker accurate?
A symptom checker is a triage tool, not a diagnosis. PetSenseAI analyses your photos, videos, and history to tell you how urgent the situation looks and what to capture for your vet, but only a licensed veterinarian can examine, test, and treat your dog.
What are the most common dog emergencies?
The most frequent true emergencies are toxin ingestion, GDV/bloat, trauma from vehicles or dog fights, breathing difficulty, heatstroke, urinary obstruction, and seizures. Together these account for the majority of after-hours emergency visits.
What counts as pale gums in a dog?
Healthy gums are bubblegum pink and refill within two seconds after you press them. White, grey, blue, or brick-red gums, or a refill slower than two seconds, indicate shock, poor oxygenation, or blood loss and need immediate veterinary care.
Should I make my dog vomit after eating something toxic?
No - not unless a veterinarian or a pet poison control line instructs you to. Inducing vomiting is dangerous with caustic substances, petroleum products, or in a dog that is already weak, seizing, or struggling to breathe.
My dog seems fine after being hit by a car. Do I still need a vet?
Yes. Internal bleeding, diaphragmatic tears, and bladder rupture can take hours to show symptoms. Any vehicle impact warrants a same-day veterinary exam even if your dog is walking and alert.
How much does an emergency vet visit cost?
In the US, after-hours emergency exams typically start around $100-$200 before diagnostics or treatment, and hospitalisation for something like bloat can run into the thousands. Call ahead so the clinic can prepare and give you an estimate.
