If your pet has a one-off vomit or one bout of diarrhoea, you should withhold food for a few hours (known as gastric rest), offer water for rehydration and feed a bland diet in the short term. Steamed chicken with no skin or bones and some boiled rice is usually sufficient for 1-2 meals (or we can provide you with a balanced prescription diet). In the majority of cases, your pet will recover without a problem.
What you should do at home
There are times when vomiting and diarrhoea become a little more severe, and that’s when you need to call on us.
You should seek advice from us if your pet:
- Vomits more than once
- Has multiple bouts of diarrhoea
- Seems lethargic or has a reduced appetite
- Might have ingested something they shouldn’t have
- Has been losing weight recently
- Has had intermittent bouts of vomiting and/or diarrhoea for weeks or months
One of the most common causes of a gastrointestinal upset in pets is a dietary indiscretion, and this is just our way of saying your pet has eaten something they shouldn’t have.
What is a dietary indiscretion?
Dogs are notorious with this, as they are typically scavengers. Common culprits for dogs include leftovers, scraps from the rubbish bin or discarded human food at the park.
Cats can be a bit fussier when it comes to what they will and won’t eat, but they can, of course, get themselves into trouble too, so you should always call us for advice if you are worried about your pet.
Ingestion of a toxin
Other causes of vomiting and/or diarrhoea include but are not limited to:
Infection from a virus, a bacteria or a parasite (such as giardia)
Conditions such as pancreatitis
Inflammatory bowel disease
A gastric obstruction from a foreign body
Other systemic diseases, such as liver or kidney disease
If you have a puppy or a kitten that is vomiting or has diarrhoea, we recommend that you always get them checked by us, as they can become dehydrated very quickly and may usually need to be hospitalised. We also need to rule out serious diseases such as parvovirus, which can be fatal in some animals.
Treatment for vomiting and diarrhoea involves medications to help reduce nausea, and intravenous fluid therapy to help rehydrate your pet. In some cases, we must perform blood tests and further imaging, such as radiographs of the abdomen, to rule out the more concerning causes. If required, we can provide your pet with a balanced prescription diet explicitly made for an upset stomach.
