Where about are you in Clackmannanshire? My yard is near tillicoultry and we use Struthers and Scott who are based in Doune they are excellent and I wouldnt think about ever changing practises. I would steer clear from Cameron and Greig based in Tillicoultry but thats my personal opinion!
Another vote for struthers and scott in Doune, i really like John he's my vet.
Loch leven equine practice in Kinross are also good with Hugh sommerville.
Cameron and Greig are ok for your basic vaccinations and if you need an immediate referal to a major horspital but otherwise they are very much a small animal and farm animal practice that aren't overly horse friendly.
