Hi
I had one, over 15 years ago, came from Bavaria. They are great wee dogs if you are mainly up a high seat, as I was then (often with clients) and took them up with me. They track well but only as good as my next dog - a GWP which could also pull down a wounded deer and double up for rough shooting. I got an offer from a German client I couldn't refuse. I'll ask around but only a few good strains in the UK.
Best
Nick
