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.
A chew article for animals comprising a body having an outer surface and spaced grooves, each of said grooves having spaced side walls together defining groove depth into said body from said outer surface, said groove depth and side walls spacing selected for receipt between said side walls and into said groove of a substantial part of an animal's tooth during chewing of said chew article even in the absence of significant deformation of said body, at least one of said side walls of at least some of said grooves having a longitudinal ridge defined thereat intermediate said depth and spaced from said outer surface of said body.
A chew toy for pets promoting dental/gingival health in its use, said chew toy comprising an elastomeric structure having an inner surface defining an interior cavity and an outer surface, said outer surface interrupted by spaced grooves formed in said structure, at least a segment of at least some of said grooves extending through said structure to said interior cavity, each of said grooves having spaced side walls together defining groove depth into said structure from said outer surface, at least one of said side walls of said at least some of said grooves having a corrugated surface configuration including a plurality of substantially parallel longitudinal ridges.
A chew toy for pets that attracts and occupies the pet while promoting dental/gingival health in its use, said chew toy comprising a body having an outer surface and spaced grooves, each of said grooves having spaced side walls together defining groove depth into said body from said outer surface, said groove death and side walls spacing selected for receipt between said side walls and into said groove of a substantial part of a pet's tooth during chewing of said chew toy even in the absence of significant deformation of said body, at least one of said side walls of at least some of said grooves having a longitudinal ridge defined thereat intermediate said depth and spaced from said outer surface of said body, said body including structure for receiving, holding and releasing edible material.
