摘要:
The spring-loaded dog toy includes a self-supporting stand composed of a generally vertical tube resting atop a flat base, and from which a generally horizontal extends atop said vertical tube to support a dog toy there from. The dog toy is usually a ball that attaches to a first spring, which is separated from a second spring via a ring stop. The second string traverses across the length of the horizontal tube and attaches at a rear end. The ring stop creates a biasing force upon the second spring. Upon pulling the dog toy and subsequent release, both the first spring and the second spring generate wild and random movement of the dog toy, which entertains and amuses a pet.
