You're welcome - thank you for your interest! I could - and do wax lyrical about them for hours! I've c&p the height and size from the breed standard below:

Size
Height: dogs: 58-62 cms (23-24½ ins); bitches: 54-58 cms (21-23 ins).
Weight: dogs: 32-38 kgs (70-84 lbs); bitches: 26-32 kgs (56-70 lbs).

I've also done a piece about them in the Pet Encyclopedia on this forum if you want to have a look - it goes into the breed history and coat care in a bit more detail.
