Common Questions

Can dogs eat cucumber skin?
Yes, cucumber skin is safe for dogs and contains additional fiber and nutrients. Just wash it thoroughly to remove any pesticide residue. If your dog has a sensitive stomach, you can peel it, but it's not necessary.
Are pickles safe for dogs?
Plain dill pickles in small amounts aren't toxic, but they're high in sodium which isn't ideal for dogs. Avoid pickles with garlic, onion, or spicy seasonings. Fresh cucumber is always the better choice.
How much cucumber can a dog eat?
Cucumbers are so low in calories that they're one of the safest treats to give freely. A few slices for small dogs or half a cucumber for large dogs is fine. As with any treat, they should supplement — not replace — a balanced diet.
