She looks about the same size as the one we play with most mornings (Sally) She is a very small one with shorter legs. I think the size of their legs varies so much in Border collies doesn't it? I love watching them doing their agility too, it's great fun to watch, they are always so keen and eager and sooooo fast, especially when they jump on that table! lol! I just love the way g.s.d.'s "sing" to you when it's time for their walk, and I really don't think there is any other dog that can match that strange "singing" they do.
