Abstract
A method of producing an enriched, natural collagen pet chew by means of vacuum sealing impregnation technology to add nutrients, flavoring, and/or anti-microbial agents to a natural, but demineralized, canine bone chew. A pet mastication article is soaked in acetic acid to reveal a flexible, chewable collagen structure. After the collagen structure is soaked and rinsed, nutrients and other agents are infused into the porous structure of the bone by means of vacuum impregnation.
