Fragrance can come from all natural or synthetic ingredients. When referenced as "fragrance" in dog shampoo, it is from synthetic ingredients. Synthetic fragrances are made a LOT of ingredients typically derived from petroleum and crude oil.
If you see an essential oil listed without the word "fragrance" in the ingredient listing, then the natural scent of the essential oil is most likely what gives that shampoo its smell.
