A consultation fee may apply (~$95 ASPCA / ~$89 Pet Poison Helpline). Pet insurance may reimburse.

Every Grape and Raisin Product: What Is Dangerous for Dogs?

Emergency contacts for any grape product ingestion:

Grapes and raisins are toxic to dogs in all forms. The following guide covers every known grape-containing product, including seasonal and regional specialities that are commonly involved in accidental ingestion. Grapes that have been through processing (juicing, drying, cooking, or baking) generally retain their toxicity. The exceptions are processed grape seed oil and grape seed extract, which have not been reported to cause acute kidney injury.

Fresh Grapes (all colours and varieties)

HIGH

Red, green, black, seedless, concord, muscat - all carry the same toxicity risk. Colour and seed content are irrelevant; tartaric acid is present in all grape flesh. Average fresh grape weighs approximately 5g. Documented minimum dose for AKI: approximately 19.6 g/kg body weight.

Typical scenario: Children sharing snacks, grapes on coffee tables, garden vines, fruit bowls.

Action: Call ASPCA (888) 426-4435 immediately.

Raisins

VERY HIGH

Dried grapes, approximately 4-5x more toxic per gram than fresh grapes. Average raisin weighs approximately 0.5g. Documented minimum AKI dose: approximately 2.8 g/kg. A 10 kg dog could develop kidney injury from approximately 56 raisins.

Typical scenario: Trail mix, cereal, baked goods, snack packs.

Action: Call (888) 426-4435 immediately.

Sultanas

VERY HIGH

Dried white (green) grapes. Same concentration of tartaric acid as raisins. More common in UK baking. Found in muesli, hot cross buns, Christmas pudding, scones, and many other UK baked goods.

Typical scenario: UK baking, muesli, granola, hot cross buns.

Action: Call (888) 426-4435 immediately.

Currants (dried Zante currants)

VERY HIGH

Small, seedless dried grapes (Black Corinth variety). Not to be confused with fresh blackcurrants or redcurrants (different plant). Common in UK baking and recipes. Carry the same toxicity risk as raisins.

Typical scenario: UK fruit cake, Christmas pudding, mince pies, Welsh cakes.

Action: Call (888) 426-4435 immediately. If you are unsure whether the currant is grape or berry, call anyway.

Grape Juice

HIGH

Concentrated grape product. Liquid form means rapid absorption. Even a small volume can deliver a significant dose of tartaric acid, especially in small dogs. Purple/red 'fruit punch' drinks may also contain grape juice.

Typical scenario: Left on low tables, spilled on floor, children's drinks.

Action: Call (888) 426-4435 immediately.

Wine (red, white, rose, sparkling)

HIGH - DOUBLE HAZARD

Contains tartaric acid (grape toxicity) plus ethanol (alcohol toxicity). Dogs metabolise alcohol very poorly. Even a small amount of wine can cause rapid intoxication, aspiration, respiratory depression, and blood sugar drops. The combination of grape toxicity and alcohol toxicity makes wine particularly dangerous.

Typical scenario: Party glasses left on low surfaces, spilled wine on the floor.

Action: Call (888) 426-4435 or your nearest emergency vet immediately.

Grape Jelly, Jam, and Preserves

HIGH

Made from grape juice or grape pulp. Contains tartaric acid. Many sugar-free versions use xylitol as a sweetener, which is separately extremely toxic to dogs even at tiny doses. Always check the label for xylitol if the product is sugar-free.

Typical scenario: PB&J sandwiches left accessible, toast with jelly.

Action: Call (888) 426-4435. If product is sugar-free, mention this - xylitol adds another serious toxicity.

Trail Mix

HIGH

Almost universally contains raisins. May also contain chocolate chips (theobromine toxicity), macadamia nuts (toxicity in dogs), and other hazardous ingredients. Dogs often eat trail mix quickly if a bag is left accessible.

Typical scenario: Hiking bags, outdoor events, desk snacks, car trips.

Action: Call (888) 426-4435 immediately. Mention all ingredients if possible.

Hot Cross Buns

HIGH

UK and Australian Easter staple. Contains sultanas and/or currants. Some recipes also include nutmeg (myristicin, separately toxic to dogs) and occasionally mixed peel. A single hot cross bun contains approximately 20-30g of dried fruit, which is a significant dose for a small dog.

Typical scenario: Easter weekend baking and purchases left on kitchen counters.

Action: Call (888) 426-4435 immediately. Seasonal hazard.

Christmas Pudding (UK)

VERY HIGH

Very dense with raisins, sultanas, and currants. Traditionally soaked in brandy or whisky before serving. The combination of very high dried fruit content and alcohol makes this one of the highest-risk foods in the UK dog-hazard calendar. A small portion can contain more dried fruit than a handful of raisins.

Typical scenario: Christmas dinner table, Boxing Day leftovers.

Action: Call (888) 426-4435 or your vet immediately. Treat as urgent.

Mince Pies (UK)

HIGH

The mincemeat filling contains raisins, sultanas, and currants. Also typically contains sugar, suet, and spices. A single mince pie contains enough dried fruit to represent a significant dose for a small dog.

Typical scenario: Christmas party tables, left on low surfaces, dog raids the plate.

Action: Call (888) 426-4435 immediately.

Fruitcake

VERY HIGH - DOUBLE HAZARD

Dense with raisins, sultanas, and currants. Many traditional recipes are soaked in brandy or rum for weeks before eating, adding alcohol toxicity. One slice of Christmas or wedding fruitcake can contain 50-100g of dried fruit - enough for a potentially fatal dose in a small dog.

Typical scenario: Christmas, weddings, celebrations, holiday gifts.

Action: Call (888) 426-4435 immediately. This is a high-priority emergency.

Oatmeal Raisin Cookies

HIGH

Each cookie typically contains multiple raisins. A single large oatmeal raisin cookie may contain 15-20 raisins, enough to create a significant risk for a small to medium dog. The oatmeal and other ingredients are not toxic, but the raisins are.

Typical scenario: Baked goods left on cooling racks, coffee table cookies, shared snacks.

Action: Call (888) 426-4435 immediately.

Raisin Bread, Cinnamon Raisin Bagels, Raisin Toast

HIGH

Raisins distributed throughout the bread. One slice of raisin bread typically contains 10-20 raisins. Cinnamon is not separately toxic to dogs at these levels, but the raisins are.

Typical scenario: Breakfast, unattended toast, kids dropping bread on the floor.

Action: Call (888) 426-4435 immediately.

Breakfast Cereals Containing Raisins

HIGH

Raisin Bran (both US and UK versions), many muesli blends, granola with dried fruit, and some porridge mixes. A bowl of Raisin Bran contains approximately 40-50 raisins. Dogs often eat cereal spilled on the floor or left in accessible bowls.

Typical scenario: Cereal bowls left on low tables, spills on the kitchen floor.

Action: Call (888) 426-4435 immediately.

Grape-Flavoured Sweets, Candy, and Chewing Gum

VARIABLE - CHECK FOR XYLITOL

Many grape-flavoured products use artificial grape flavouring (concord grape flavouring compounds), which do not necessarily contain real grape. However, many sugar-free varieties contain xylitol, which is extremely toxic to dogs. Check the ingredient list. If xylitol is present, treat as an emergency regardless of grape content.

Typical scenario: Candy dishes, children's sweets, sugar-free gum in handbags.

Action: Call (888) 426-4435 immediately if xylitol is present. For real-grape products, call regardless.

Stollen (German Christmas Bread)

HIGH

Traditional German Christmas bread containing raisins and sultanas throughout. A typical slice contains a significant raisin content. Common as a holiday gift and particularly dangerous during the Christmas period.

Typical scenario: Christmas and winter holiday gifts, festive food platters.

Action: Call (888) 426-4435 immediately.

Panettone (Italian Christmas Bread)

HIGH

Italian Christmas bread traditionally containing raisins and candied fruits. The fruit is distributed throughout the bread. A single portion contains multiple raisins.

Typical scenario: Christmas and New Year celebrations, gifts from Italian delis.

Action: Call (888) 426-4435 immediately.

Grape Seed Oil and Grape Seed Extract

LOW (but not recommended)

Processing removes the tartaric acid fraction from grape seed oil. Grape seed extract supplements are similarly processed. Neither has been reported to cause the same acute kidney injury as whole grapes, raisins, or juice. However, they are not necessary for dogs, there is no proven benefit, and we do not recommend them without veterinary input. This exception does not make any other grape product safe.

Typical scenario: Supplements added to dog food by owners.

Action: Not a poison control emergency, but consult your vet before adding any supplement.

Garden Grapes and Wild Vines

HIGH

Fresh grapes from garden vines or wild vines carry the same toxicity risk as supermarket grapes. Dogs with access to gardens with grape vines are at risk during growing season, particularly when grapes fall to the ground and become accessible.

Typical scenario: Dogs with garden access, autumn grape drop.

Action: Fence off grape vines. Call (888) 426-4435 if ingestion occurs.

A Note on Xylitol in Grape-Flavoured Products

Many sugar-free versions of grape-flavoured products (jelly, gum, candy) contain xylitol as a sweetener. Xylitol is a separate and additional toxin for dogs, causing rapid blood sugar drop and liver failure at doses as low as 0.1g/kg. Even products without real grape may be dangerous due to xylitol.

For detailed information on xylitol toxicity, see candogseatstrawberries.com/xylitol.

Frequently Asked Questions

Can dogs eat sultanas?
No. Sultanas are dried white grapes and carry the same toxicity risk as raisins. They should never be given to dogs. Call ASPCA (888) 426-4435 if your dog has eaten sultanas.
Can dogs eat hot cross buns?
No. Hot cross buns contain sultanas and/or currants, which are toxic to dogs. Some recipes also contain nutmeg, which is separately toxic. A hot cross bun eaten by a dog is a veterinary emergency. Call (888) 426-4435 immediately.
Can dogs eat fruitcake?
No. Fruitcake contains raisins, sultanas, and currants (all toxic), and many recipes include brandy or other alcohol (separately harmful). Both the dried fruit content and the alcohol make fruitcake particularly dangerous.
Can dogs drink grape juice?
No. Grape juice contains concentrated grape compounds including tartaric acid. Even a small amount can be dangerous, especially for small dogs. Call poison control if your dog has consumed grape juice.
Is cooked grape safe for dogs? (e.g. in a sauce)
No. Cooking does not destroy tartaric acid. A reduction of grape juice or wine still contains the toxic components. Any sauce, glaze, or condiment containing grapes, wine, or grape juice should be kept away from dogs.
