I'm currently with Poplar Vets. Dr. Lukas there seems knowledgeable and was willing to switch Monty from Caninsulin to Lantus.
I don't really have a bench mark to compare to other vets as I've only seen this one. I'm usually able to get appointments at short notice and the vet technicians are VERY good and kind. Henrika, who works there as a vet tech, has done some cat sitting for me in the past and charges reasonable rates.
