They're not a breed I would ever willingly own, or really reccomend tbh.
Which sounds horrible after the last post, but I don't mean it in a horrible way at all.
I've never met a nasty one, they've all been without exception, lovely, friendly and madder than a box of frogs.
They smile you know, like actually raise their lips when they're happy and dance about on their paws when they're excited... they're happy and excited quite a lot of the time, it'd drive me insane, rofl.
They're pretty trainable, but, they'll ignore you if something more exciting comes along and well, apparently everything is exciting...
I suppose if you've loads of time and energy, masses of patience, a good sense of humour, you don't mind a dog that dances on its tiptoes almost anytime anything happens and don't mind if what it wants to do isn't going to always want to be what you want it to it might be ideal?
They're definitely not for me, but I'm pretty fond of the ones I've known, just always glad I'm taking them to their house and not mine after a walk, lol
