Yorkie vomiting or diarrhoea — what owners should do first
Vomiting or diarrhoea can happen after a food change, stress, scavenging, infection, parasites, pain, toxins, or another illness. With a Yorkie, the safest approach is to look at the whole picture early instead of waiting for a tiny dog to become obviously very sick.
Call a vet urgently if
- Vomiting or diarrhoea is repeated, severe, bloody, black, or watery.
- Your Yorkie is weak, collapsed, shaking, bloated, crying, or unusually quiet.
- Water cannot stay down or your dog seems dehydrated.
- A puppy, senior, very small, diabetic, pregnant, or frail Yorkie is affected.
- There may have been toxin, medication, bone, plant, spoiled food, or foreign-object access.
Useful checks before you phone
- When symptoms started and how often they have happened.
- Whether appetite, drinking, gums, energy, breathing, or toileting changed.
- Any new food, treats, bones, table scraps, travel, stress, or grooming.
- Whether other pets in the home are also unwell.
- Your Yorkie's age, weight, known conditions, and current medication.
Dehydration can become the real danger
A single mild tummy upset in an otherwise bright adult dog is different from repeated vomiting, ongoing diarrhoea, or a Yorkie that is quiet and not drinking. Small dogs can lose fluid and energy quickly, so early veterinary advice is often the low-risk option.
Do not give human medicine, force food, or try strong internet remedies. Keep your Yorkie warm, quiet, and safe, offer water, and contact your vet if symptoms are more than mild or if anything about the dog seems wrong.
Vomiting vs regurgitation — know the difference
It sounds pedantic, but the difference genuinely matters to your vet.
- Vomiting is active. The Yorkie heaves, retches, and brings up partly digested food or yellow bile from the stomach. There is usually a warning — drooling, licking lips, looking miserable.
- Regurgitation is passive. Food or water comes back up almost immediately after eating, often with no real effort. It usually points to the oesophagus rather than the stomach.
If you can describe which one you saw, how often, and what it looked like, your vet has a head start. A phone video of the episode helps even more — vets genuinely use those.
Why Yorkies get sick so fast
Yorkies carry almost no buffer. A 3 kg dog has a tiny stomach, fast metabolism, and very little body fat to fall back on. What is a mild 24-hour bug in a big dog can become dehydration and low blood sugar in a Yorkie within hours. That is not drama — it is arithmetic.
Two things matter more than anything else: water staying down and energy levels. A Yorkie that is drinking, keeping water down, and still interested in life is a very different case from one that is not.
The common causes — what is behind a sick tummy
Here is the honest list of what usually causes vomiting or diarrhoea in a Yorkie, roughly in order of how often owners actually hit them:
- Dietary indiscretion. The classic. Braai scraps, fatty mince, a stolen sausage, leftover bones, something found on a walk. This is the number one cause — and it is also the easiest one to prevent.
- Sudden food change. Switching brands overnight without a transition. Always mix the new food in gradually over a week.
- Empty-stomach nausea (bilious vomiting syndrome). Yellow bile in the morning or between meals. Small dogs with fast metabolisms and long gaps between meals are prone to it.
- Parasites. Worms, giardia, coccidia — especially in puppies and rescue dogs with unknown histories.
- Gastroenteritis or infection. Something picked up from other dogs, parks, or contaminated water. Puppies are at highest risk before vaccinations are complete.
- Pancreatitis. A painful pancreas inflammation often triggered by a sudden high-fat meal. Yorkies are a small breed that does not handle rich food well. This needs a vet, full stop.
- Toxins. Rat poison, snail bait, chocolate, xylitol (in sugar-free gum), grapes, certain plants, or household chemicals. If there is any chance of toxin access, say so immediately when you phone.
- Foreign objects. Bits of toys, fabric, plastic, or bones that got swallowed and are now stuck or irritating the stomach.
- Stress. New home, new people, a move, boarding, or a change in routine. Rescue Yorkies especially can vomit or get loose stools from stress alone.
- Underlying illness. Kidney disease, liver problems, hormonal conditions, or other chronic disease can show up as vomiting or diarrhoea first.
You do not need to diagnose it — that is the vet's job. But the more honest detail you can give about what changed recently, the faster they can help.
Safe home care for a mild upset
For a single mild episode in an otherwise bright adult Yorkie, this is the sensible first step while you watch closely:
- Offer small amounts of water frequently. Ice cubes to lick can also work.
- Rest the stomach for a few hours — but do not fast a Yorkie for a full day.
- Then introduce tiny, bland meals: plain boiled chicken and white rice, or a vet-approved sensitive diet.
- Keep portions small and frequent rather than one big bowl.
- Phone your vet if symptoms happen more than twice, or appetite and energy drop.
Dehydration checks at home
- Sticky or dry gums instead of moist, slippery ones.
- Reduced energy — a Yorkie that normally bounces but is now flat.
- Sunken eyes or a dull coat.
- Slow skin-spring: gently lift the skin between the shoulders; it should spring back quickly.
- Less peeing than usual, or dark strong-smelling urine.
Suspect dehydration? Phone the vet the same day. Do not wait to see if it fixes itself.
What not to do
- Do not give painkillers, anti-diarrhoea medicine, antibiotics, or supplements without vet guidance.
- Do not wait overnight if your Yorkie is weak, repeatedly sick, or cannot keep water down.
- Do not assume it is only food if there is pain, shaking, blood, bloating, or collapse.
- Do not let a vomiting dog chew bones, rich treats, or random leftovers.
- Do not switch foods abruptly or feed a rich 'special' meal while they recover.
What the vet will do
A vet will ask about the history above, feel your Yorkie's belly, check hydration and temperature, and may run tests — faecal sample, blood work, or imaging — depending on what they find. For a tiny dog, they may recommend fluids under the skin or a short hospital stay to stabilise. That sounds scary, but it is exactly why early calls beat late emergencies.
Rescue Yorkies and tummy upsets
If your Yorkie is a recent rescue, add two things to the picture. First, stress: a new home is a huge adjustment, and stress alone can cause vomiting or loose stools. Second, unknown history: rescue dogs may arrive with parasites, dietary gaps, or a gut that has never seen decent food. That is not a judgement on the dog or on you — it is just why rescue Yorkies often need a gentle, consistent diet and a settling-in period before their stomachs behave.
Read the rescue Yorkie settling-in guide → if you are in those first weeks, and go easy on food changes until the routine is steady.
Frequently asked questions — Yorkie vomiting and diarrhoea
- Is vomiting or diarrhoea dangerous for a Yorkie? It can be. Tiny dogs have less reserve, so repeated vomiting, diarrhoea, weakness, blood, dehydration, pain, or symptoms in a puppy or senior Yorkie should be treated as urgent. A single mild episode in an otherwise bright adult dog is usually less concerning, but watch closely and phone for advice if anything feels off.
- Can I give human medicine for Yorkie diarrhoea or vomiting? No. Do not give human medicine unless a vet specifically instructs you. Common painkillers and anti-diarrhoea products are unsafe for dogs — especially small dogs — and can hide what is actually wrong.
- What is the difference between vomiting and regurgitation? Vomiting comes from the stomach with real heaving. Regurgitation is passive — food or water comes back up almost immediately after eating, with no effort. The causes are different, so tell your vet which one you saw.
- Why is my Yorkie vomiting yellow bile? Often empty-stomach nausea (bilious vomiting syndrome), common in small dogs with long gaps between meals. Splitting meals into smaller, more frequent portions usually helps, but confirm the pattern with your vet.
- What should I feed a Yorkie with an upset stomach? Rest the stomach briefly, offer water frequently, then move to small bland meals like plain boiled chicken and white rice or a vet-approved sensitive diet. Keep portions tiny and frequent. Do not fast a Yorkie for long, and do not switch straight back to rich food or treats.
- How can I tell if my Yorkie is dehydrated? Check for sticky or dry gums, reduced energy, sunken eyes, a slow skin-spring test, and less peeing than usual. In a Yorkie, dehydration can set in fast — if you suspect it, phone the vet the same day.
- How long should vomiting or diarrhoea last before I call a vet? Call immediately if there is blood, black stools, repeated vomiting, weakness, pain, bloating, or if a puppy or senior is affected. For a single mild episode in a normal adult, watch closely for a few hours — but more than twice, or a drop in appetite and energy, means a vet call.
- Why do Yorkies get pancreatitis? It is common in small breeds and often triggered by a sudden high-fat meal — braai scraps, fatty mince, sausage, rich treats. Signs include vomiting, a tucked-up painful belly, and being off food. It needs a vet; do not try to manage it at home.
- Can my Yorkie catch a tummy bug from the park or another dog? Yes. Gastroenteritis, parvovirus, and parasites like giardia spread easily where dogs meet. Puppies are especially at risk before vaccinations are complete. Mention park or dog-contact history to your vet — it changes what they test for.
- Should I fast my Yorkie when they vomit? A short rest is fine, but do not fast a Yorkie for a full day. Toy breeds have tiny reserves and can slide into low blood sugar and dehydration quickly. Offer water frequently, then small bland meals. If water cannot stay down, call the vet.
Vomiting and diarrhoea are connected to the bigger health picture
A sick tummy is often one piece of a larger pattern — diet, dental disease, stress, or an underlying condition. Start with the main Yorkie health guide to see how it all fits together. If your Yorkie is also off their food, the not-eating guide → and shaking guide → cover the other classic warning signs. And for the feeding side — what is safe, what is not, and how to change food without upsetting the gut — see the Yorkie feeding guide → and the safe human foods reference →.
If there is any chance of rat poison, snail bait, chocolate, xylitol, grapes, or a toxic plant, do not wait for symptoms — phone your vet or the nearest emergency clinic immediately and say what was eaten, how much, and when.
