Can dogs eat it?

Can dogs eat cucumber?

Yes, in moderation Yes. Cucumber is about 96% water and very low in calories, a good treat for dogs watching their weight. Skip pickles.

Why

Half a cup of cucumber slices has about 8 kcal, against about 40 in a medium dog biscuit (AKC). The skin and seeds are fine. Pickles and gherkins bring salt and spices.

How to give it safely

Wash, then slice into pieces sized for your dog. Do not give a whole cucumber.

This is general guidance, your vet sets the actual schedule. Puppies, small dogs and dogs with a health condition can react to smaller amounts. Check with your own vet before changing what your dog eats.

Other foods people ask about

Asparagus Yes, in moderation Yes, cooked and cut small. Raw spears are hard to chew and digest, and the asparagus fern in the garden is not safe. Aubergine (eggplant) Yes, in moderation Yes, a little plain cooked aubergine. The leaves and flowers of the plant are the parts to avoid. Beetroot Yes, in moderation Yes, a little plain beetroot, cooked or raw. Skip it if your dog has had bladder or kidney stones, and do not panic at pink wee. Bell peppers Yes, in moderation Yes, plain sweet peppers of any colour in small amounts. Never chilli or jalapeño peppers. Broccoli Yes, in moderation Yes, in very small amounts. Plain raw or steamed broccoli is fine, but too much irritates the stomach. Brussels sprouts Yes, in moderation Yes, a sprout or two, cooked and plain. More than that can cause wind and an upset stomach.
