Mmmmm
Not sure that any of the sighthounds would be 'that' suitable for competitive agility.
Certainly cant think of any pedigree ones....... in general they are not overly impressed with that sort of thing, and their long legs are not really designed for turning on slippy floors at speed, or running up and down things.... although jumping and running fast they can do.
You may, if you would consider a lurcher, rather than a pedigree, do far better with a small lurcher, one with whippet/working beardie/collie/bedlington type blood.......closer to the ground meaning less danger of falling, and more speed, and much more trainable than pure sighthounds.
That said, ive seen wolfhounds doing agility (although not particularly fast or elegantly!) so they CAN do it, just a lot of them wouldnt entertain the idea!
