Every dog owner faces the same 11pm question sooner or later: is this something to worry about, or am I overreacting? Dogs can't tell us what's wrong, and they often hide discomfort, so it falls to us to read the signs. This guide sorts them into three groups — emergencies that mean go now, warning signs worth a prompt visit, and how to judge urgency when it isn't obvious. Knowing the difference saves lives at one end and needless worry at the other.
Emergencies: go to a vet immediately
These can't wait. If you see any of them, contact an emergency vet and go:
- Difficulty breathing — laboured, gasping, choking, or gums turning blue or very pale.
- Collapse, fainting, or unable to stand or wake properly.
- Signs of heat stroke — frantic panting, bright red gums, wobbliness or collapse in the heat. Begin cooling on the way. → Heat Stroke in Dogs and Cats
- Suspected poisoning or eating something toxic. → Foods You Should Never Feed Your Dog or Cat
- A swollen, hard abdomen with unproductive retching — this can signal bloat/GDV, a rapidly fatal emergency especially in large, deep-chested breeds.
- Seizures, especially repeated or prolonged.
- Severe bleeding, major trauma (a fall or road accident), or a suspected broken bone.
- Inability to urinate, or repeated unproductive attempts.
- Repeated vomiting or diarrhoea, especially with blood, or with a bloated, painful belly.
- Signs of severe pain — crying out, trembling, aggression when touched, or extreme restlessness.
- A bitch struggling in labour.
When in doubt at this level, call an emergency clinic and describe what you're seeing — they'll tell you whether to come in.
Warning signs: book a visit soon
Not emergencies, but your dog signalling that something's changed. Book a check within a day or two:
- Appetite or thirst changes — eating much less, or drinking noticeably more (a common early sign of several diseases).
- Lethargy or a clear drop in energy that lasts.
- Vomiting or diarrhoea that's mild but persists beyond a day, or keeps recurring.
- Limping, stiffness, or reluctance to exercise, jump or climb stairs.
- Persistent bad breath, or trouble eating — often dental. → Pet Dental Health
- Weight change up or down, even gradual.
- Skin problems — persistent itching, hair loss, sores or a smell.
- Lumps or swellings — get any new lump checked.
- Changes in toileting — straining, accidents, or a change in frequency or appearance.
- Behaviour changes — new irritability, hiding, confusion or restlessness.
- Eye or ear problems — redness, discharge, squinting, or head-shaking.
How to judge urgency when you're not sure
Most situations aren't dramatic, and the honest answer is often "watch and decide." A useful framework:
- What is different from your dog's normal — and how much?
- Is it getting worse, staying the same, or improving over hours?
- Is your dog otherwise bright, eating and drinking — or flat and off?
- Does it involve a red-flag system — breathing, repeated vomiting, collapse, severe pain, the abdomen? If so, treat it as urgent.
A reasonable rule: if a sign is severe, worsening, or involves breathing/collapse/severe pain, don't wait. If it's mild and your dog is otherwise well, monitoring for 24 hours and then seeing a vet if it hasn't resolved is often sensible — but never ignore your instinct that "something's off." You know your dog.
A symptom checker can help you think through the signs and gauge urgency, but it supports your decision rather than replacing a vet's judgment — AI assists; experts decide.
Prevention beats emergencies
Many emergencies are the visible end of problems that were quietly building. Regular check-ups, keeping your dog lean, dental care and age-appropriate screening catch a lot before it becomes a crisis.

Frequently asked questions
How do I know if my dog's problem is an emergency? Treat it as an emergency if it involves difficulty breathing, collapse, seizures, suspected poisoning, heat stroke, a bloated/painful abdomen with retching, severe bleeding or trauma, inability to urinate, or severe pain. When in doubt, call an emergency clinic and describe the signs.
My dog is vomiting — should I see a vet? A single vomit in an otherwise bright, well dog can often be monitored. See a vet promptly if vomiting is repeated, contains blood, comes with a bloated or painful belly, or is paired with lethargy, or if it continues beyond a day. Deep-chested breeds retching unproductively need immediate care.
My dog seems a bit off but is still eating — can it wait? Often you can monitor a mild change for 24 hours in a dog that's otherwise bright and eating, then see a vet if it hasn't improved. But trust your instinct, and don't wait if anything is severe, worsening, or involves breathing, collapse or severe pain.
Can a symptom checker tell me if my dog needs a vet? It can help you think through the signs and judge urgency, but it's a support tool, not a diagnosis — a veterinarian makes the call. AI assists; experts decide.
