Dogs can’t tell us what hurts, so it’s on us to notice changes in body, behaviour, and routine. Some problems can wait for an appointment, while others are true dog emergency signs that need immediate care. Use this quick guide to spot key vet visit signs, common dog sick symptoms, and decide when to see vet help.

How to decide when to see vet care (simple triage)

Emergency now: trouble breathing, collapse/unresponsive, heavy bleeding/major trauma, seizure, suspected bloat, can’t urinate, toxin/foreign object.
Same-day call: sudden, significant change (repeated vomiting/diarrhea, obvious pain, marked lethargy, not eating for a day—sooner for puppies/seniors).
Book soon: mild but persistent issues (itching, recurrent ear trouble, weight change, limp lasting 24–48 hours).

When in doubt, call your clinic—clear details help them triage safely.

Dog emergency signs: get veterinary help immediately

Breathing distress: rapid/laboured breathing, open-mouth breathing, blue/pale gums.
Collapse/extreme weakness or unresponsiveness.
Seizures: first-time, repeated, or lasting more than a few minutes.
Suspected bloat (GDV): unproductive retching, swollen/tense belly, drooling, rapid decline.
Severe bleeding/major trauma (hit-by-car, deep wounds, big falls).
Straining or inability to urinate (especially males).
Heatstroke: heavy panting, bright red gums, vomiting, collapse after heat.
Toxins/foreign objects: human meds, rodenticides, chocolate, grapes/raisins, xylitol, antifreeze, sharp items, string.
Severe allergic reaction: facial swelling/hives, vomiting with weakness, breathing changes.
Uncontrolled vomiting/diarrhea with weakness or blood.
Eye injuries: sudden squinting, cloudy/bulging eye, obvious pain.

On the way: keep your dog calm and warm, avoid human meds, bring toxin packaging, and take photos/videos (vomit, stool, breathing, limping).

Same-day call + easy-to-miss vet visit signs

Vomiting/diarrhea: repeated, bloody, very watery, or >24 hours.
Not eating: 24 hours (12 hours for puppies/small breeds).
Pain/behaviour changes: yelping, stiffness, trembling, guarding, sudden aggression when touched.
Respiratory: persistent cough, wheeze, gagging, new “honking” cough.
Other: excess drinking/urination, new limp, swollen belly, unusual discharge/odour.
Often missed: bad breath/oral pain (drooling, dropping food, chewing one side), weight/coat changes, new lumps, persistent licking/itching, recurring stool/sleep/stamina or accident changes.

Puppies, seniors, and what to track before you call

Puppies dehydrate fast; seniors and dogs with chronic disease or long-term meds can deteriorate quickly—call earlier for vomiting/diarrhea, weakness, coughing, confusion, appetite or thirst/breathing/energy changes.

Track: when it started, worsening, frequency; food/water intake; urination/stool; energy/mobility; possible exposures (trash, new treats/meds, boarding, parks).
