Emergency Vet Warning Signs Every Owner Should Know

Knowing the difference between 'monitor at home', 'book a routine appointment' and 'go to an emergency vet right now' can genuinely save your pet's life. This is not a substitute for veterinary advice, but a guide to recognising when urgency matters.

Go to an emergency vet immediately if your dog or cat shows:

• ●Difficulty breathing, gasping, or blue/pale gums — this is always an emergency
• ●Collapse, seizures, or sudden inability to stand or walk
• ●Repeated, unproductive retching with a visibly swollen abdomen (a classic sign of bloat/GDV in dogs, which can be fatal within hours without treatment)
• ●Suspected poisoning — chocolate, grapes/raisins, xylitol, lily plants (cats), rodenticide, or any human medication
• ●Straining to urinate with little or no output, especially in male cats — this can indicate a urinary blockage, which is life-threatening within 24–48 hours
• ●Heavy bleeding that won't stop with direct pressure after several minutes
• ●A distended, painful abdomen combined with weakness or pale gums
• ●Suspected broken bones, especially with the limb at an unnatural angle
• ●Eye injuries, particularly a visibly bulging or prolapsed eye
• ●Being hit by a car, even if your pet 'seems fine' afterwards — internal injuries are not always immediately obvious

Book a same-day or next-day appointment (not necessarily emergency) if:

• ●Vomiting or diarrhoea that's persisted for more than 24 hours without other severe symptoms
• ●Limping that hasn't improved after a day of rest
• ●Reduced appetite lasting more than a day, especially in cats — cats that stop eating entirely for more than 24 hours need prompt attention
• ●Mild lethargy without other worrying symptoms
• ●A single episode of vomiting or diarrhoea in an otherwise bright, active pet — worth monitoring closely rather than immediate panic

How UK out-of-hours emergency vet care works

Most daytime vet practices in the UK don't provide their own overnight or weekend emergency cover — instead they contract with a dedicated out-of-hours provider (Vets Now is the largest UK network). When you call your usual vet outside opening hours, the answering message will normally direct you to the correct emergency number or location.

Save this number in your phone before you need it — searching for an emergency vet while your pet is in genuine distress costs precious time. Ask your registered vet practice which out-of-hours service they use and note the address, as it may not be the same building as your daytime practice.

If you don't have a registered vet yet, that's the first thing to fix — use our vets directory to find and register with a nearby practice today, not during an emergency.

Cost expectations

Out-of-hours emergency consultations typically cost significantly more than a daytime visit — often £150–£300 for the initial consultation alone, before any treatment. This is one of the strongest arguments for pet insurance: it removes cost as a factor in an already stressful, time-critical decision.

When in doubt

If you're genuinely unsure whether a symptom warrants an emergency visit, call the emergency vet line and describe what you're seeing — most services will triage over the phone and tell you whether to come in immediately, monitor, or book a routine appointment. It's always better to make that call than to guess.
