Vegetable oil in dog food
Vegetable oil is a general term used for any oil of plant origin. In general it is used to refer to lower-quality oils like rapeseed, palm or corn oil. It is added to some dog foods as an alternative to more expensive (and more nutritious) fats and oils like animal fat, olive oil or sunflower oil. As always, it is best to look for a food where each ingredient is accurately identified.
