Shoot! My female Rottweiler is 8 years old and she's faster than me!!! I've never had a dog as fast as Dexter. My daughter had a yellow lab that loved to chase frisbees and we could never throw it far enough that he couldn't catch it. I don't know if Dex is faster yet but I suspect he will be.
Well Kian is 6 months old and he can run pretty fast from the other dogs when he wants. When we are at the dog park they have a hard time keeping up.
A friend of mine has a 2 year old V which Kian cannot keep up with...YET ;D
Lili is HELLA fast, she's fast enough to catch a rabbit, but since we didn't teach them to hunt she just runs close to the rabbit then turns back to me lol, she can run through our deserts like a little deer ;D
