The Tumbo Tugger is a perfect addition to any household. This toy uses a strong and safe bungee cord to create a fun stretching force for your puppy to pull against in your outside yard. The medium and large dogs can play tug-of-war with the strength of the outside layer, and when they let go, the ball toy launches off for them to chase down like a game of fetch. It’s easy to hang and store, and it’s made of a durable plastic that will last for years.
