Highly Toxic

Grapes, raisins, sultanas, and currants are extremely dangerous to dogs. The exact toxic substance is unknown, but ingestion can lead to sudden acute kidney failure.

Why is it dangerous?

• Unpredictable: Some dogs can eat grapes without issue, while others may go into kidney failure after eating just one or two. There is no known “safe dose.”
• Raisins are worse: Because they are dried and concentrated, raisins are even more potent than fresh grapes.

Symptoms

• Vomiting (often within a few hours)
• Lethargy
• Loss of appetite
• Abdominal pain
• Decreased urination (sign of kidney shutdown)

Action: Immediate veterinary treatment is critical to protect the kidneys.
