When vomiting becomes urgent and what details help triage. Use this page to decide what to gather before you call and which warning signs should move quickly.
Repeated vomiting is more concerning than a single mild episode, especially when a pet cannot keep water down, seems painful, is flat, has blood present or may have swallowed something unsafe.
Vomiting can be caused by stomach upset, pancreatitis, obstruction, toxins, infection, organ disease, medication effects or pain. The pattern and the pet's overall condition change urgency.
Emergency signs are not always tidy. A pet may have one obvious problem, but the risk often depends on the whole picture: breathing, gum colour, pain, alertness, recent trauma, toxin exposure, appetite, hydration and toileting.
Note timing, frequency, appearance, appetite, water intake, diarrhoea, possible toxins or swallowed objects. Avoid human medicines and repeated food changes while the cause is unclear.
Keep the handling simple and calm. If your pet is painful, frightened, weak or struggling to breathe, repeated checking can make things worse. Phone early so the team can help you decide how to move them safely.
We may check hydration, abdominal comfort, temperature, blood tests, imaging, anti-nausea treatment, fluids or admission depending on severity.
Urgent care begins with the problems that threaten life or comfort first. Once the patient is safer, we can make better decisions about imaging, blood tests, medication, observation, surgery or referral.
A bright pet who vomited once is different from a flat pet who will not eat, cannot keep water down or has repeated vomiting and diarrhoea. The whole patient matters.
Young, old, small, pregnant, chronically unwell or medicated pets can become dehydrated or unstable faster than a healthy adult pet.
Tell us how many times vomiting or diarrhoea has happened, whether there is blood, what food or objects may have been eaten, and whether your pet is drinking, urinating and moving normally.
If several pets are affected, or if there was possible rubbish, toxin, bone, foreign body or medication exposure, that changes the conversation.
Human anti-diarrhoea, pain or nausea medicines can be unsafe for pets. Repeated diet changes can also make it harder to tell whether the gut is recovering.
If your pet is unwell, it is better to ask what is safe before trying multiple approaches from the cupboard.
A recovering pet should become brighter, keep water down, regain appetite, pass more normal stool and show less abdominal discomfort. Improvement should be steady, not only a brief quiet patch after exhaustion.
If signs return, blood appears, pain increases or appetite does not come back, the situation should be reassessed.
When you call, start with the most urgent-looking sign, then give the timing. For example: trouble breathing for ten minutes, vomiting six times since breakfast, no urine since last night, hit by a car one hour ago, or possible toxin exposure at noon.
It also helps to say whether your pet is bright or flat, eating or refusing food, walking or unable to stand, breathing normally or with effort, and whether the gums look pink, pale, grey or blue.
If the signs sound unstable, we may recommend urgent assessment even before every detail is known. That is because some problems can only be made safer with oxygen, pain relief, fluids, monitoring, imaging or hands-on examination.
Coming in quickly does not mean every outcome is already decided. It means the patient needs a safer place for the next decision to be made.
Vomiting is common, but persistent vomiting can dehydrate and weaken pets quickly.
A change that is still treatable can become more difficult once shock, dehydration, pain or organ stress develops. That is why the safest advice is often to call before the situation becomes clearer.
Repeated vomiting, blood, collapse, bloating, severe pain, toxin exposure, inability to keep water down or a very young, old or fragile pet should prompt urgent advice.
If you are unsure whether the sign is serious enough, call. A short triage conversation is usually safer than sitting with a worsening pet while trying to decide from a webpage.
Tell us what happened, when it started, what your pet weighs if you know, whether medication or toxins are involved, and whether breathing, gum colour, urination, appetite or alertness has changed.
Photos, product packets, videos or previous medical history can help when they are easy to gather. They should never delay leaving if your pet is collapsing, breathless, bleeding heavily or unable to urinate.

Emergency pages are only a starting point. If your pet is struggling, deteriorating or showing one of the warning signs above, contact us or the after-hours service so the next step can be triaged.
When in doubt, call earlier. Early advice can prevent unsafe home treatment and helps us prepare before you arrive.
