Why cucumber is fine for dogs
Cucumber is a hydrating, very low-calorie treat — great for dogs watching their weight.
How much can a dog eat?
Treats — including cucumber — should make up no more than about 10% of your dog's daily calories. Start with a small amount the first time to make sure it agrees with your dog, and serve it plain, with no added salt, sugar, oil or seasoning.
A few caveats
Puppies, seniors and small breeds need smaller portions. Dogs with health conditions (diabetes, kidney disease, a sensitive stomach) should only have new foods with your vet's okay.
What about their everyday food?
Treats are only part of the picture — your dog's main diet matters most. Paste your dog food's ingredients into the WoofScore checker to see how it grades A–F.
