Why a 6 kg dog reacts to 10 redcurrants
Small dogs process volume differently than larger breeds—what seems like a few berries to you is a sudden bulk for their digestive system. Your dog's vomiting likely comes from the stomach stretching rapidly rather than toxicity, especially since redcurrants themselves aren't harmful. The stems or leaves mixed in could add mild irritation, but the main issue here is mechanical overload from eating quickly.
Watch the vomit for any stems or undigested berries, which confirm this was likely a simple stomach upset. If the vomiting stops within two hours and your dog shows interest in water, the worst has passed. However, persistent retching or dry heaving means the stomach lining is still aggravated and needs vet attention to prevent dehydration.
What blood tests reveal at the clinic
Vets typically run a basic blood panel in cases like this not because of the redcurrants themselves, but to check for hidden triggers—like pancreatitis or an infection—that could explain why your dog reacted so strongly to a small amount. They'll look at kidney values and electrolytes, especially if there's been multiple vomiting episodes, since small dogs dehydrate faster.
The vet may also palpate your dog's abdomen to rule out a blockage, though this is rare with soft berries. If your pup seems uncomfortable when touched near the ribs or belly button, mention it—this could signal gastritis needing medication. Most dogs go home with instructions for a bland diet after such tests.
When to skip the next meal
Withholding food for 6–8 hours gives the stomach time to reset, but water should still be offered in tablespoon amounts every 20 minutes. If your dog keeps down three rounds of tiny water sips, you can try adding a teaspoon of plain boiled rice or pumpkin. The key is restarting meals at 25% of the normal portion size to avoid restarting the vomiting cycle.
Some dogs bounce back quickly and act hungry immediately—resist the urge to feed a full meal. Overloading the stomach again is the most common reason for a second round of vomiting. Instead, divide the usual dinner portion into four mini-meals over the next 12 hours, gradually increasing if no more vomiting occurs.
Signs that mean calling the vet back
While most cases resolve within a day, watch for lethargy that worsens instead of improving after napping—this suggests dehydration or blood sugar drops in small dogs. Dry gums or skin that tents when gently pinched are emergency signs. Also note if vomit changes from food/water to yellow bile or foam, which indicates an empty stomach still cramping.
One episode of vomiting is normal; four or more in six hours isn't. Similarly, a single loose stool isn't alarming, but diarrhea with straining or blood warrants a callback. Your vet may prescribe gastrointestinal protectants if irritation persists, but antibiotics usually aren't needed unless a fever develops.
