How wonderful that you met one! I have been reading the breed handbook and there is an article in there written by a man who shoots pheasant on the prairies of South Dakota with Munsters - so you do have them in the States but possibly as here in the UK, they are not very common. The breed was introduced here (from Germany where it originates) in the 70s and so is still fairly new. And they are very controlled in the breeding programme so as not to get inbreeding - the mother of our pup was imported from Germany and his father has German blood through his parents. The great thing about them is that the working and show stock are the same - no disctinction like with some breeds where you get 'ugly workers' and 'beautiful nutters'!
Oh my goodness! You are only the second person I have ever known who had one of these dogs. The other was a couple on exchange from the Royal Airforce with the USNavy. Well, the husband was on exchange and his wife and dogs came with! They were the sweetest and smartest dogs. Congrats on your new baby!
