27 symptoms for dogs, most urgent first.
A firm, swelling belly with unproductive retching, drooling, restlessness, and pacing. Bloat (GDV) can kill within hours and is most common in large, deep-chested dogs.
Suddenly going down and being unable to get up, even briefly. Heart problems, internal bleeding, and toxins can all look like this.
Healthy gums are pink and refill quickly after a gentle press. Pale, white, gray, or blue gums signal shock, blood loss, or oxygen trouble.
Collapse with paddling, stiffening, or loss of awareness. Keep hands away from the mouth, clear the area, and time the seizure.
When it changes: A first seizure, any seizure over 3 minutes, or more than one in a day all mean go now.
If you saw or suspect your pet get into something harmful, act before symptoms start. Grab the packaging and call a poison hotline or vet right away.
Obvious effort to get air: heaving sides, stretched neck, or blue-tinged gums. Do not wait to see if it passes.
Pink, red, or brown urine warrants a same-day call. Bring a fresh sample if you can catch one.
Struggling to stand, especially in the morning, is a classic sign of joint pain or arthritis. Dogs hide chronic pain well, so do not write it off as aging.
Dropping food, stretching the neck to swallow, or drooling while trying to eat suggests something stuck, a throat problem, or dental pain.
Asking to go out constantly and producing small amounts each time is the classic pattern of a urinary tract infection.
Walking like they are drunk, dragging a paw, or standing on the top of a foot without correcting it points to a nerve or spine problem, not just a sore muscle.
When it changes: Sudden inability to use the back legs is an emergency now.
Thinning patches, symmetrical bald areas, or hair coming out with skin flakes can signal parasites, allergies, or hormonal disease. Book a visit; this is rarely urgent but rarely self-resolving.
Raw, wet, painful patches that appear fast and grow by the hour, usually from self-trauma over an itch. They rarely heal without treatment.
Flinching, yelping, or pulling away when a limb is handled points to injury that needs an exam, not just rest.
Panting after play is normal. Heavy panting at rest, at night, or with a stressed posture is not; it can signal pain, heart or lung trouble, or heat stress.
When it changes: Panting with weakness, pale or brick-red gums, or vomiting on a warm day is heat stroke territory: emergency now.
Posturing repeatedly with little urine produced usually means infection, stones, or inflammation. Same-day attention keeps it from getting worse.
When it changes: No urine at all over several hours is an emergency, especially in male dogs.
A friendly dog growling when touched, sudden clinginess, or hiding usually means pain or illness, not stubbornness. Trust the change, not the explanation you can think of.
Bite wounds are worse than they look: small punctures can hide deep damage and infect quickly. Any bite from another animal deserves a same-day call.
When it changes: Heavy bleeding that does not stop with firm pressure is an emergency now.
One soft stool in an otherwise normal dog can be watched. Keep water available and note what they ate in the last day.
When it changes: Diarrhea past 24 to 48 hours, blood, black tarry stool, or diarrhea with weakness means call your vet.
Licking one spot, the air, or surfaces more than usual. A licked-raw spot, or air licking with a gurgling stomach, points to pain or nausea.
When it changes: Licking that breaks the skin or lasts more than a few days deserves a vet visit.
Occasional gagging or throat clearing can follow excitement or drinking fast. Watch whether it repeats and whether anything comes up.
When it changes: Repeated gagging, gagging with a swollen belly, or signs of choking mean call or go now.
More tired than usual and reluctant to do normal activities. A quiet day happens; track eating, drinking, and interest in walks.
When it changes: Lethargy past 24 hours, or with any other symptom on this page, means call your vet.
Brief grooming is normal. Persistent licking suggests irritation, infection, or urinary discomfort.
When it changes: Combined with straining or blood, call your vet the same day.
A mild limp after hard play can be rested for 24 to 48 hours with short leash walks only.
When it changes: A limp that persists past 48 hours, a leg that cannot bear weight, or crying in pain means call your vet.
Skipping one meal while otherwise bright is usually fine in an adult dog. Note anything else that changed the same day.
When it changes: No food for more than 24 hours, or refusing water, means call your vet. For puppies, call the same day.
An occasional scratch is normal. Track whether it is one spot or all over, and check for fleas with a flea comb at the tail base.
When it changes: Scratching that interrupts sleep, breaks skin, or continues past a week deserves a vet visit.
A single vomit followed by a normal, bright dog can be watched at home. Hold food briefly per your vet's advice and reintroduce water slowly.
When it changes: Repeated vomiting, blood, vomiting with lethargy, or trying to vomit with nothing coming up means call now; the last one can be bloat.
