I have gone over this topic way too many times in the states and here in Thailand.
"Picking the right vet!" They can be very costly in the states as well as here in Thailand.
Lets see.. Jeab drove over 60 kilometers today to see two different vets to do a simple umbilical hernia operation. the quote from the 1st vet was 5700 Thai baht (or $180 USD) and the second vet wants 1500 Thai baht ( or $47.00 USD) to do the same operation at the 3rd month after all the vaccines are given. Now, call you local vets in the country that you live in and ask them the cost to a 3 month old puppy for the same operation.
Do I trust a vet here over the USA we will say?? Same as anything.. it all depends who that vet is and where you are going. The prices vary all over the USA and Europe as they do here. Be wise about who you take your puppy to. Doing a DSC operation is a wee bit more involved then a UH operation and these seem to be the only two operations one may have to do outside of castrating a male and spaying a female.
In Thailand the cost of spaying a female TRD varies from 1000 baht to 1500 in most vet offices or clinics. The males are slightly cheaper. In USD that is $32 - $45 USD. Now, this is where all vets get you... the pills and capsules they prescribe to you for your puppies and dogs. The liquid worm medicine and that great wormer world over Dontle +.. The prices at you vet are 2-100 times more. This is how the vets make the money.. 2-5 baht in actual cost at a chemist the vets will 10-20 times that per pill or capsule. So, if you can get pharmaceutical drugs from a chemist like here in Thailand sell all drugs across the counter, it is better you buy just a wee bit from the vet and the rest from your local chemist or drug store.
So to re-cap... most vets in Thailand are useless pill pushers and will tell you to go to another vet to do any sort of surgury that has to do with using a blade to cut the tissue of the animal.. and good vets who know their busines are trained in the US and learn how to "inflate" the costs as that is a class for sure on most vet schools in the USA and Europe..
