Digestive signs can be simple, but they can also be the first clue that a pet is painful, dehydrated, obstructed, poisoned or dealing with a condition that needs testing. The hard part for owners is knowing when an upset stomach is reasonable to monitor and when waiting becomes risky.
This page brings together the common digestive situations we see in dogs and cats: vomiting, diarrhoea, appetite loss, abdominal pain, swallowed objects and recovery after treatment. It is designed to help you choose the safest next step without making every mild sign feel like an emergency.
One isolated vomit in a bright pet is different from repeated vomiting, vomiting with lethargy, a painful belly, blood, collapse, bloating, a young puppy or kitten, or a pet who may have swallowed something. The same applies to diarrhoea: duration, hydration, appetite, blood, pain and energy level all change the urgency.
Good digestive care starts with the story. What changed, what your pet could have eaten, whether stools or vomit contain blood, whether there is retching without producing vomit, and whether appetite or thirst has changed can all guide what we do next.
The first question is whether your pet is stable. Hydration, pain, temperature, gum colour, heart rate and abdominal comfort help us decide whether home care is reasonable, whether medication and monitoring are enough, or whether testing should happen quickly.
The second question is what the digestive signs could be pointing toward. Diet changes, parasites, infection, pancreatitis, inflammatory disease, toxins, foreign material, endocrine disease, kidney or liver problems and surgical conditions can all look similar at home. That is why the same symptom can lead to different plans in different pets.
Blood tests, x-rays, ultrasound, faecal testing and repeat examinations are most useful when they help answer a specific question: is there dehydration, organ stress, obstruction, severe inflammation, pancreatitis, bleeding, a mass, or a reason your pet is not recovering as expected?
Sometimes the safest plan is staged. A stable pet may start with treatment and careful monitoring. A pet with red flags may need imaging, fluids, pain relief or surgery discussion sooner. The goal is not to test everything; it is to avoid missing the problem that changes the outcome.
Use this when stools are loose, urgent, bloody, recurring or not settling.
Helpful when your pet is off food, nauseous, painful or not acting like themselves.
How examination, blood tests, imaging and sampling help guide digestive decisions.
Watching appetite, hydration, stools, comfort and response to treatment after a visit.
How to think about vomiting episodes, patterns, urgency and what details help the vet.
When a sore or swollen belly may signal a problem that should not wait.
Digestive red flags that should be triaged quickly rather than watched at home.
Seek urgent advice if vomiting is repeated, your pet cannot keep water down, the abdomen looks bloated or painful, there is collapse, pale gums, blood, severe lethargy, a known toxin exposure, or a swallowed object. Cats who stop eating and small puppies or kittens can become unwell quickly.
If you are unsure, call. A short conversation about what you are seeing can help decide whether your pet should be seen now, watched closely, or booked for a non-urgent appointment.
If your pet is vomiting, has diarrhoea, is not eating, or seems uncomfortable, we can help you decide whether this needs urgent care, a same-day visit, or a monitored plan.

Useful if there is any chance your pet ate a toy, bone, sock, string, corn cob or other risky item.
