Hi Robina,
maybe you saw this thread:
vet recommendation in Zurich
Summerain mentioned:
As for recommendations wise, it really depends on where in Zurich you live. I used to bring my dog to Dr Buchler in Hongg. Dr Buchler is very experienced, extremely professional and a highly skilled surgeon. He did my dog's castration and removal of an extra toe with minimal scarring (in fact, I cant find any!). His details are:
Dr. med. vet. Emil Büchler
Hohenklingenstrasse 45
8049 Zürich
Tel. +41 (0) 44 341 07 07
Good luck!
