Dorothy has prodigious jumping skills. I know I'm biased, but really--Bulldogge Can Jump. We would like to enroll her in an agility class eventually, and I really think she would love it.
In the meantime we keep her limber by having her jump for sticks outside (and on to benches and walls) and for toys indoors.
I tried to capture Dorothy flying through the air on film, but my camera is very slow. Here are two pictures of her towards the beginning of her jumps, though, and they do show how she can get quite airborne.
Not a bird, not a plane, but a bulldogge! Go, Dorothy, fly like an eagle!
