Hello Sadie,
Weclome to the board and hopefully to Weimaraner ownership :) I have a 19 month old male Weim and he certainly keeps life interesting :D He's fast asleep on the sofa at the moment recovering from the shock of seeing his "favouritest-ever-in-the-whole-wide-world" doggy football floating down the river (I'm not the best thrower in the world, oops!). Didn't tempt him to get his feet wet though, think he's a mutant actually, most Weim's seem to relish a dip. Me, I've got a HPR who's scared of ducks! Oh well, we all love him, bags of character and fantastic with my two kids, 7 & 8. They're not good at being left alone though so please bear that in mind when you do get one, they just want to love you for ever all the time, even if it's only resting their head or a paw on your sweaty foot (sweaty from being out in soggy fields for hours throwing poxy balls into the river!) . You've probably read up and found out lots about them as you've been an admirer for so long so I'll stop waffling now.
One thing though, have you got your heart really set on purchasing a puppy or would you consider a rescue? They have some youngish dogs in there who need re-homing for things like marriage break-ups etc. They're not all monster-dogs! Was just thinking that if you don't want to show or breed then you'd have the joys of owning a Weim with none of the "nasty" bits like toilet-training. If you did decide you wanted to "do" something with him, other than enjoy him just as a loyal companion, you could give agility a bash. Although you can't show a rescue dog I'm pretty sure you can compete in agility. Tohme is very well versed in most things Weim (and writes some excellent articles re. nutrition too, even in the WCGB Newsletters!) so if she happens along again, try to nab her if you are interested.
Good luck in whatever you decide and I hope you get more years of enjoying a loving companion than you do of tearing your hair out and turning prematurely grey
