Can Dogs Eat Sultanas?

NO — dogs should NOT eat sultanas. Sultanas (dried grapes) contain a toxic compound that causes acute kidney failure in dogs, even in small amounts. No safe quantity exists. Keep sultanas strictly away from your dog's food and treat them as a severe poisoning risk.

Why Are Sultanas Dangerous for Dogs?

Sultanas are dried grapes, and grapes (fresh and dried) are one of the most reliably toxic foods for dogs. The exact toxic mechanism is not yet fully understood by veterinary science, but the active compound appears to be a fungal mycotoxin or an unknown organic compound that concentrates in grapes and their dried forms (raisins, currants, sultanas).

The toxin causes acute kidney damage, leading to acute kidney injury (AKI) and potentially progressing to total kidney failure if not treated immediately. The damage can be irreversible, especially if treatment is delayed.

The greatest concern is that individual sensitivity is unpredictable. Some dogs show dramatic symptoms from a single sultana; others may ingest larger quantities without apparent immediate signs. However, subclinical kidney damage may still be occurring, making the damage apparent only after several days.

How Much Is Toxic?

The toxic threshold is dose-dependent and highly variable:

• As few as 4–8 sultanas (or 20–30 grams) have triggered kidney failure in sensitive dogs.
• Small dogs (under 10kg): Any quantity above 5–10 sultanas is dangerous.
• Medium dogs (10–25kg): 10–20+ sultanas increase risk significantly.
• Large dogs (25kg+): Higher absolute quantities are needed, but toxicity is still possible.

The problem: there is no reliably safe amount. Individual tolerance is unpredictable. Because of this, veterinary guidance is absolute: any ingestion warrants immediate veterinary contact, not observation.

Symptoms to Watch For

Symptoms typically appear within 24–72 hours, but kidney damage begins immediately:

• Vomiting (may be persistent)
• Diarrhoea or loss of appetite
• Lethargy or depression
• Abdominal pain or discomfort
• Excessive thirst and increased urination (or later, decreased urination)
• Dark-coloured or no urine (sign of kidney failure)
• Breath odour (from uraemia)
• Tremors or collapse (late-stage)

Critical point: Some dogs show no symptoms while kidney damage is occurring. Blood work is the only reliable diagnostic tool.

What to Do If Your Dog Eats Sultanas

1. Contact your vet or Animal PoisonLine immediately (01202 509000) — do not wait to see if symptoms develop.
2. Know the number of sultanas and your dog's weight.
3. Do not delay treatment. Early decontamination and kidney support are essential.
4. Induce vomiting if advised (typically safe within 2 hours of ingestion).
5. Do not assume "just one" is safe — vets recommend treatment even for minimal ingestion.
6. Bring your dog in for blood work — baseline kidney values (creatinine, BUN) must be checked immediately and again 48–72 hours later.

Veterinary treatment includes gastric decontamination (if recent), IV fluids to flush the kidneys and maintain hydration, activated charcoal, and serial blood work monitoring kidney function. Hospitalisation is often necessary.

Prevention Tips

• Keep sultanas in a sealed, high cupboard — not in a bowl on the kitchen counter.
• Do not share cereal, granola, or trail mix with your dog — many contain sultanas or raisins.
• Check baked goods: Cakes, biscuits, and breads often contain sultanas.
• Be cautious at picnics and holidays — dried fruits are common in festive foods.
• Educate children: Never give your dog sultanas as a "healthy snack."
• Clean up immediately: Sweep under dining chairs to catch dropped sultanas.
• Use safe treats: Offer carrot sticks, apple slices (without seeds), or vet-approved dog treats.
