Goji berries are safe for dogs
Neither fresh or dried goji berries (or wolfberry) are toxic to dogs. They are high in vitamin A, riboflavin, iron, copper, and selenium. As with other fruits, they do contain sugar so only feed them as an occasional treat. If it’s your first time feeding your dog goji berry, observe them for any adverse effects. Goji berries imported from China may have high levels of insecticide and fungicide residue.
