SLEEPING ON MY FOOT!

I want to buy a herding ball for my Corgi. Any advice on what size? He's 8 months old, 25 lbs. And TONS of energy.

I have an African grey parrot and a corgi. At night time we bring the parrot into the bedroom w us and put him on a large perch next to the bed. Eventually the parrot will flutter over to my side of the bed for his nightly head scratches.

The Corgi goes crazy; running from side to side and whining. Is this jealousy or is he disturbed by the wing flutter or all the above?
