there is a good vet
The ONLY vet I know of is between Fruisa and the Riu Hotel on the right hand side before the crossroad going to Macau. They do NOT do surgery tho...closest vet that does surgery is in Higuey....It's a husband and wife team..really sweet but a little wacky and VERY primitive....if there is an emergency grab a taxi and FLY to Santo Domingo..the alternative is scarry!!
The other vet in Bavaro is great for shots, skin infections, etc, etc
Good Luck
