Is lemon safe for dogs?

Lemon is a very sour citrus fruit. The peel and pith contain oils that are more concerning than the juice or flesh. The juice and flesh are very sour and most dogs avoid them on their own, but the peel, pith and seeds contain essential oils and compounds that can cause stomach upset, so lemon is best not offered as a treat.
