There are no vets in Meribel, and the nearest one is down at Moutiers. I have used them in the past and found them fine.
There is another highly regarded Vet in Bozel but I have no details for that one at this moment.
The Vet in Moutiers is on the right side as you approach the roundabout from Meribel. You have to take a very sharp right turn on the roundabout itself. Always best to call first and make an appointment if possible.
