This device is a little motorized wheel that throws a ball for dogs. The great thing is the wide open top so the dog can drop the ball into themselves. Then fetch the ball.
Initially I was think if this when my elbow start hurting after hitting tennis balls for my dog.
We could make a small one that can toss a ball about 10 feet for small dogs in an Apartment.
This would be a great help for people who have difficulty throwing or getting out of their home.
We could make then light weight with wheels so people could easily set it up at a park.
With several dogs it could be a game. to get the ball and then return it to the machines hopper.
They would come with variable power, and be plug in, or battery operated.
We could also make one with air compression.
Spring loaded would be another option. Pulling back on a lever could be easier then throwing the ball, allowing greater portability.
