PlantFunGrape vine Toxic?
Grapes, raisins, currants, sultanas and pomace from Vitis vinifera are highly toxic to dogs, potentially causing fatal acute kidney failure
Cats are not highly susceptible to acute kidney injury caused by consumption of Vitis vinifera fruits
All plant parts of Vitis vinifera are confirmed to be toxic per published horticultural toxicology literature
FAQ
Is Grape vine toxic to Humans?
No confirmed acute human toxicity data for regular consumption; seek medical attention if adverse reactions occur after large quantity ingestion (Non-toxic)
Is Grape vine toxic to Cats?
No significant acute kidney injury reported, cats are generally not highly susceptible to toxicity from this plant (Low)
Is Grape vine toxic to Dogs?
Within 24 hours: vomiting, diarrhea, lethargy, anorexia; later: polydipsia, polyuria/oliguria/anuria, ataxia, abdominal pain, neurological symptoms, acute kidney failure occurring 24-72 hours post ingestion that can be fatal if untreated. Lab abnormalities include elevated serum creatinine, urea, hypercalcemia, hyperphosphatemia, elevated amylase, and proteinuria (High)
Is Grape vine toxic to Horses?
No available confirmed toxicity data for horses, consult a veterinarian immediately if ingestion occurs (Low)

Toxicity Snapshot
First Aid & Prevention
First 30 Minutes
- • If ingestion occurred within 2 hours and the affected animal is conscious, induce vomiting if safe to do so
- • Administer activated charcoal to absorb residual toxins
- • Transport the animal to a veterinary emergency facility immediately
Contact Vet Immediately
- • If a dog has ingested any amount of grapes, raisins, or any part of the grape vine
- • If symptoms like vomiting, diarrhea, lethargy, or changes in urination appear after suspected ingestion
- • If you suspect any pet or livestock has consumed any part of this plant
Prevention
- • Keep all grape products (fresh grapes, raisins, currants, wine pomace) out of reach of dogs
- • Do not feed any grape-derived products to dogs
- • Avoid growing grape vines in areas accessible to unsupervised dogs
Treatment & Prognosis
- • Decontamination: induce emesis or perform gastric lavage within 12 hours of ingestion
- • Administer activated charcoal after decontamination to prevent further toxin absorption
- • Provide intravenous fluid diuresis for a minimum of 48 hours to support renal function
- • Monitor renal function parameters (serum creatinine, urea, electrolyte levels) for 72 hours post ingestion to detect acute kidney injury early
Professional Toxicology
• Toxicity is linked to high concentrations of dicarboxylic acids (tartaric acid, oxalic acid) present in all plant parts, which cause renal tubular epithelial cell damage leading to acute renal failure in susceptible species (dogs)
