The present invention provides an improved method of administering a medicinal, dental or nutritional agent to a non-human animal, such as a domesticated dog or cat. The method comprises mixing a liquid composition in a mixer at various speeds and pressures for a period of time pouring the liquid composition onto a conveyor belt propelled by polymer rollers, wherein the polymer rollers allow the components to advance on the conveyor belt without adhering to the belt evenly distributing the composition on the belt with the use of a knife heating the composition in one or more hot-air chambers obtaining a film comprised of the composition cutting the film into strips and then administering one or more of the strips to the non-human animal by placing the strip under the tongue of the animal, i.e., by sub-lingual administration.
