A horse is the only thing that would work as a mount, but I'd also like having a dog again as a pet (obviously not a mount

).
Obviously, a cow would be stupid to ride.
There's really no kind of creature that you would be able to ride due to size, except a balvarine, which probably wouldn't
let you ride it anyway, and there's no way you could keep a spell like turncoat casted 24/7 to keep it from killing you.
A flying broomstick? What is this, Harry Potter?
