hey, i know of two breeders in uk.
firstly there is jannet holland (who is the one who set up the web site the alaskan kleekai assosiation of GB) i have not personally met jannet but i know she has both the long haird and short and has all three size.
toy: upto and including 13''
minature: over 13'' and upto and including 15''
standard: over 15'' and upto and including 17'' (im not sure if this last one has now been changed to upto 18'', seem to be different from different sorces)
and there is also the wonderfull michael and mahari lynch who own the ''Highlandks''
this is where i got my little boy from, the are near sterling in scotland (which is not exactly local as i live near london) but i went to see them before i agreed to get a pup from them and they have three kleekais, one standard dog, one standard bitch, and one minature bitch.
the thing i liked about them was the fact that the dogs whrere first and formost valued family pets and where very well trained, no jumping up, not overly vocal and def no signs of aggression or shyness just really happy dogs.
my boy came from there standard boy and minature girl, so i was lucky to get to meet mum and dad together

i think they also get studs in from jannet.
i could not fault them in any way, they are lovely people who love there dogs dearly and are very responable breeders (as in having contract to have the pups back rather than them going to rescue shelters and not letting just anyone have a pup)
i hope this help you, they are a fantastic breed who are so loving and playfull not to mention beautiful! my little boy kaskae is 11 months now
