My sister has had three of these and I did a presentation on the breed when I did my City & Guilds in Canine Studies quite a number of years ago so had to do a lot of research - not easy with a rare breed! They are a guardian breed who like plenty of space and benefit from lots of socialisation when young, as most dogs do anyway. As for training, they respond well to positive reinforcement training but they will also use their intelligence to make their own decisions if they believe their owners to be mistaken!

In other words, do not expect them to obey just because yo say so - they have to agree too!

But, they can make good companions if treated with respect and kindness, not with dominance methods - use these and they dig their heels in hence the 'stubborn' reputation. They are not always the most reliable off lead as if they see something in the distance that requires investigation, hey may decide to go and see what it is first. Just the flock guardian instinct but some owners find it annoying! Beware if you are house proud as they literally moult like camels during their moults!

They are a beautiful breed but a prospective owner should do a lot more research rather than just 'liking the look'.
A quick google brought this site up (I always think that rescue sites give a clearer description of what breeds are like)
