Abstract
A chew article for animals that promotes dental and gingival health, oral exercise, interactive play, and reduction of problem chewing. The article includes a body of elastomeric material having an outer surface interrupted by spaced grooves. Side walls of at least some of the grooves have a corrugated surface configuration including a longitudinal ridge or ridges extending lengthwise intermediate groove depth and spaced from the outer surface of the body. An interior cavity is provided having a constricted access thereinto from without the body, a segment of at least some of the grooves extending through the body and into the cavity thereby defining plural laterally moveable rib portions of the body, the detached rib portions aiding maintenance of more optimal scraping orientation of the ridges when the article is in use.
