Yes, dogs can have cucumber as an occasional treat. VCA lists cucumbers as a good option for dogs when fed in moderation. The ASPCA also lists cucumber as non-toxic to dogs. Washed cucumber cut into bite-size pieces, with seeds and peel removed as the ASPCA suggests. The ASPCA says you can even add cucumber to a pet's water, and suggests removing seeds and peel before serving.

For the children

A job: Be the label reader. Before a grown-up shares any food with the dog, check this page, and ask a grown-up if the food is not on it.
