A probiotic composition, delivery device, method of forming, and a method for delivery are disclosed. The composition may be in the form of a spray, mist, film, or the like suitable for use with any pre-formulated pet food product, whether in solid or liquid form, and further to the use of the spray directly on the coat or skin of an animal. The probiotic spray may also be applied directly into a cavity of the animal, for example into its mouth or nasal passages. The probiotic composition provides multiple strains or species of viable bacteria that provide health benefits when ingested, and is shown herein primarily for consumption by or use on/in animals, though the invention is not limited in any way to use strictly for animal intake, but may also be suitably used for human ingestion.
