Lotti is correct, we recently had our 6 month old pup spayed in Yambol.
The vet is called Yanko and is gorgeous, and speaks English and what's more he cares about animals.
The process was very different from our Staffordshire Bull Terriers op in the UK.
Immy has been done before her first season, me and my friend Jayne, took both our dogs on the same day.
They were both given pre meds, and we were asked to walk them for about 20 minutes nearby the surgery, which is clean and modern as Jude says.
They were both then given their anaesthetic one after the other and we stayed with them in the surgery this time until they were under.
Me and Jayne went off for a coffee, and about an hour and a half Yanko called us to say they were ready.
The beauty of it, is that you are with the dog until it goes under, and there when they come round, they are not left there all day like my Staffie was.
Neither dog needed to wear a collar, as although there was a little irritation the first day, they did not touch their wounds.
After 10 days they were returned to have the stitches out.
The cost for the spay was but which also included a microchip insertion, and painkiller which lasts about 36 hours, was 123 leva.
