At an emergency vet, patients are not seen in order of arrival. They are seen in order of how sick they are. This process is called triage. Understanding it can make a long, worrying wait easier, and helps clinic teams explain it to clients.
This guide is part of our pet emergency guide.
What is veterinary triage?
Triage is a rapid assessment, usually by a veterinary nurse or technician, done within minutes of arrival. Its purpose is to identify pets whose lives are in immediate danger so they can be treated first.
What the triage team checks
Triage focuses on the major body systems in a quick, structured way. A common approach checks:
- Airway and breathing: is the airway clear, how fast and hard is the pet breathing?
- Circulation: gum colour, capillary refill time, heart rate and pulse quality.
- Neurological status: alertness, ability to stand, seizures.
- Bleeding and obvious injuries.
- Temperature and pain level.
Typical priority levels
| Level | Examples | When seen |
|---|---|---|
| Immediate (life-threatening) | Not breathing, severe breathing distress, cardiac arrest, active seizures, severe bleeding, shock | At once |
| Urgent | Bloat, blocked male cat, major trauma in a stable pet, recent poisoning | Within minutes |
| Semi-urgent | Vomiting with lethargy, limping with significant pain, moderate wounds | Within an hour or so, depending on caseload |
| Non-urgent | Mild skin problems, ear infections, minor limping, mild diarrhoea in a bright pet | After more critical patients |
Hospitals use their own scales and terms; this table is a simplified illustration.
What this means for you
- Long waits are a good sign for your pet: it means the team judged your pet stable.
- Tell staff if anything changes while you wait: breathing, collapse, vomiting or new bleeding. Your pet will be reassessed.
- Consider urgent care for non-urgent problems to avoid long emergency waits. See emergency vet vs urgent care.
Phone triage
Many hospitals also triage by phone, asking about breathing, gum colour, alertness and what happened. Calling ahead lets them prepare and can tell you whether to come in immediately.
For clinics: making triage smoother
Clear triage protocols, a structured intake form, and fast access to the patient’s history, allergies and current medications help teams triage accurately. Digital records that travel with the pet make referrals and emergency visits safer.
