Dog toys provide a means for enjoyment and exercise for dogs (and other pets). As is well known, balls and other pet toys which can bounce and be pounced on and grabbed and pulled by pets mouth are very popular. Dogs love chasing and retrieving such bouncing toys and tugging against the opposite pulling of their owners. While conventional toys of this type are enjoyed by dogs, after a period of play time dogs may lose interest in a toy before their owners do; many dog owners have experienced a sudden abandonment of interest by their dogs in such situations.
