Can Dogs Eat Frozen Grapes? No — Freezing Does Not Reduce Grape Toxicity

This food is NOT safe for dogs. Keep it away from your pet.

Frozen grapes are not safe for dogs. Freezing does not eliminate grape toxicity — frozen grapes cause the same fatal kidney failure as fresh grapes. The cold temperature may actually make them more appealing to dogs creating additional danger.

Warning Signs & Symptoms

Same as fresh grapes: acute kidney failure from any amount. Freezing does not reduce toxicity. Cold texture may increase palatability for dogs making accidental consumption more likely.

Did you know?

Frozen grapes became a popular diet snack in the 1970s and 1980s as a low-calorie alternative to candy and ice cream. The frozen texture extends the eating experience making each grape take longer to consume. Dog owners began offering frozen grapes as treats based on the assumption that a food safe for humans must be safe for dogs — a dangerous assumption that has led to numerous emergency vet visits. The increased palatability of the cold texture may actually cause dogs to consume more grapes than they would at room temperature.

What You Need to Know

Frozen grapes are particularly dangerous because the cold temperature and firm texture make them appealing treats — some owners have unknowingly given dogs frozen grapes as treats. Freezing does nothing to reduce the toxic compounds. Any frozen grape exposure is the same emergency as fresh grape exposure.
