4-minute read · Loyal Saints Food Safety Library
Quick answer
Yes — cucumbers are safe, hydrating, and very low in calories, making them an excellent treat for dogs (especially overweight ones). They're about 96% water. Serve in appropriately sized slices to prevent choking, and introduce gradually to avoid stomach upset.
Cucumbers are a crunchy, hydrating, ultra-low-calorie treat — about 96% water — making them a great choice for dogs watching their weight. They provide small amounts of vitamins K, C, and potassium, and their high water content helps with hydration on hot days.
Serve cucumbers in appropriately sized slices or sticks to prevent choking, particularly for small dogs. Introduce gradually, as too much of any new vegetable can cause mild stomach upset or gas. Plain cucumber only — skip any seasoning or pickled cucumbers (pickles are high in salt and often contain onion/garlic).
