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.
