Why?
Cucumbers are mostly water making them extremely low in calories and hydrating. They contain vitamins K, C, and B1, as well as potassium and magnesium.
How much can dogs have?
A few slices is plenty. Perfect as a low-cal treat for dogs on a diet.
What to watch out for
Cut into small slices to prevent choking. Avoid pickled cucumbers — the brine contains high sodium and spices that are not good for dogs.
