From doing a google search these would have to probably be the closest to the standard that i've seen...

I also seen some are breeding Mini Aussies x Corgi "Auggie"
There is website that i came across the other day thats breeding "Miniature/Toy Aussies" here in Aus. ..but if your friends are in the US they would have hundreds of breeders to choose one from.
oh GayleK i'd love to find a Male around that size
