My dog got into some snap peas that were left out and look a bit mouldy — is this dangerous?

Short answer

Fresh snap peas are safe, but mouldy ones pose a different risk. Mould can produce mycotoxins that may cause vomiting, diarrhea, or tremors in dogs, especially if a large amount was consumed. Remove any remaining spoiled peas and offer your dog plenty of fresh water. Monitor closely for the next 24 hours for signs of stomach upset, lethargy, or unusual behavior, and contact your vet if you see any of these symptoms.
