Some years ago we took our dogs to a vet near Brugg, but he has retired, and his practice has been taken over, and moved to Windisch as of April 2011.
Here are the new details:
Dr. med. vet. Jacqueline Hochstrasser
Dohlenzelgstrasse 23
5210 Windisch
056 441 4166
I have not been there personally but I understand English is not a problem. She is recommended by someone on this website,
www.hundi.ch (it is in German and if you can understand German you can see what the locals say...which is always very interesting).
