Our newest, most amazing product is the Invincible Geckos by Plush Puppies. Dogs love squeaker toys but become bored after they stop making noise. Invincibles Geckos are stuffing-less toys that contain patent-pending squeakers. They keep squeaking, even after being punctured. Invincibles are great for dogs who lose interest in plush toys after they have “killed” the squeakers. Perfect for all dogs with sharp teeth! We have tested the Invincible gecko and have been amazed with the results. We have Gecko's in 2 sizes. The smaller size contains 2 invincible squeakers. The larger size has a whopping 4 invincible squeakers.
