Abstract
A dog chew made of extruded, edible material has a brush-shaped head at one end and a tail at the other. The brush-shaped head and tail are connected to the head by a shaft. The brush-shaped head is provided with segments (for example six segments) with spaces between the segments adapted to be more easily manipulated in a dog's mouth, so that smaller pieces break off when a dog bites and chews the article. Thus, the brush-shaped head may contain individual segments having an elliptical cross section, so that a dog's tooth can work between the individual segments or “bristles.” Elsewhere on the profile of the dog chew, stepped surfaces are avoided in favor of smooth, rounded surfaces, so that the dog chew is more easily handled in the dog's mouth and has an aesthetically pleasing appearance.
