Can dogs eat Currants?
No - Currants is toxic to dogs
No - dried currants are grapes, and they carry exactly the same kidney risk as raisins and sultanas. One thing worth knowing: fresh blackcurrants and redcurrants are a completely different plant and are not in the same league. If a recipe or label just says "currants", assume dried grape.

How much is safe?
None. Currants is never safe for dogs - not even a little.
None. There is no amount of dried currant that is known to be safe for a dog, and because sensitivity varies so much between individuals, a handful that one dog shrugs off can put another on a drip. Treat any amount as worth a phone call.
Symptoms to watch for
Vomiting or diarrhoea usually appear within six to twelve hours, often with pieces of fruit visible. After that: lethargy, going off food, belly pain, weakness and dehydration. The serious sign comes later - producing less urine than usual, or none at all, which points to the kidneys and is an emergency.
Think they have eaten Currants?
Ring your vet straight away, before any symptoms appear - do not wait to see whether your dog seems unwell. Early treatment to empty the stomach and protect the kidneys is far more effective than treatment started once signs show. Tell them roughly how much and how long ago.

What happens
Dried currants are small dried grapes, so they carry the same danger as raisins. The suspected culprit is tartaric acid, which grapes contain in quantity. Dogs lack the transporters other species use to clear organic acids, so it accumulates in the cells of the kidney tubules and can cause sudden acute kidney injury. Two things make this one nastier than most: the reaction is idiosyncratic, meaning some dogs are badly affected by a small amount while others get away with more, so no dose is reliably safe - and drying concentrates the fruit, so a currant packs more punch than a grape of the same weight. Currants also hide inside food rather than sitting in a bowl: Eccles cakes, teacakes, scones, Christmas pudding, mince pies and hot cross buns are all built on them.

Common questions
Are currants as dangerous as raisins?
Yes. Dried currants, raisins and sultanas are all dried grapes and carry the same risk of sudden kidney injury. Being smaller does not make a currant safer - if anything the small size means more of them go down before anyone notices.
My dog ate blackcurrants from the garden - is that the same thing?
No, and this is a genuinely confusing bit of naming. Fresh blackcurrants and redcurrants are Ribes berries, a completely different plant from the grapevine, and they are not linked to the kidney injury that grapes cause. A few off a garden bush are not the emergency that a handful of dried currants would be, though a lot of any fruit can upset a stomach. The dried currants in baking are the ones to worry about.
How many currants are dangerous for a dog?
Nobody can give you a safe number, and that is the whole problem. The reaction is idiosyncratic: some dogs develop kidney injury from a small quantity while others tolerate more, and there is no way to know in advance which sort of dog you have. Vets treat any meaningful ingestion rather than gambling on it.
