This article implies that veterinary skill gains while you are training your pets: http://www.uoguide.com/Pet_Training both in the 2nd paragraph and the 2nd bullet under "Notes". I can't quite tell if this is implying passive gains while your pet is fighting, or if it simply is saying that while training your pet you will be healing it, thus in turn "raising your veterinary skill". It sounds to me like it raises passively while your pet is fighting. Can anyone confirm this on OSI? Because if it indeed gains passively, then it should be implemented in ServUO, because right now it doesn't.
