2. Description of Prior Developments
Pet chew toys have long been available in numerous sizes, shapes and materials. It is well known that latex rubber is a highly desirable material to use in making pet chew toys, but unfortunately latex rubber is not as aesthetically pleasing to human consumer. As such, latex rubber pet chew toys are less popular.
Although vinyl plastic material is much more durable and rigid than latex rubber and has been used in the manufacture of pet chew toys, pets such as dogs do not seem to enjoy chewing on the harder vinyl material as much as on the softer latex material.
