Chuckie the Flying Squirrel
Just grasp Chuckie the Squirrel by one of his paws, and fling him like a flying disc.
His spinning paws put on quite a show for your dog, and he always lands on his feet - so Rover can easily pick him off the ground. If your dog likes to swim, just throw Chuckie into the pool or lake - he floats.
At the end of the day, your dog will get a workout. And you won't throw your arm out or have to keep grabbing a tennis ball soaked with saliva! Measures 10" X 10".
