The Details: Dogs

Cucumbers make an excellent low-calorie snack for dogs. They are hydrating and crunchy, which many dogs love.

Because they're low in calories and fat, they're a smart choice for overweight dogs who need a healthy treat instead of high-fat biscuits. However, feed them as an occasional snack rather than a meal replacement. Too many new veggies can upset your dog's stomach.

The Details: Cats

Cucumbers are also safe for cats in small amounts. They're a good source of hydration if your cat likes the crunch and the high water content.

Cats are strict carnivores, so plants won't provide their main nutritional needs. A tiny piece every now and then won't hurt, but keep portions very small.

Serving Tips

Even though cucumbers are safe, you shouldn't just hand over a whole one. Proper prep keeps your pet safe from choking hazards and digestive issues.

For dogs:

  • Wash thoroughly
  • Cut into small rounds or pieces
  • Can be served with or without peel

For cats:

  • Wash thoroughly
  • Cut into tiny pieces
  • Remove seeds if large

Skip the salted, pickled, or spiced cucumbers. Pickles often contain garlic, onions, and high amounts of sodium, which can harm pets. Stick to plain, fresh cucumbers.

The Bottom Line

Cucumbers are a refreshing, hydrating treat that both dogs and cats can enjoy safely in moderation. They make a fantastic low-calorie reward for dogs watching their weight.
