What pet euthanasia services are available in Chiang Mai, and what are the legal considerations?

Just to follow up in case anyone else in Chiang Mai runs into a similar situation.

The last couple of days the puppy started getting worse, until this morning she was not eating at all, and started regular convulsions, so I called up The Veterinary office of Dr. Nook (you can look up the office & contact number on the Internet) to see if they could help, which they said they could do, but to bring in the bill from the last vet that did the diagnosis of 'distemper'.

So wrapped her up in her small bed and drove down to Dr. Nook's office on a street just south of the Old City (about 20 minutes) but by the time I got there the puppy had already passed away.

To make it clear, They will NOT provide this service lightly and you will need to show them (with documentation) that there is no hope of recovery (I already had the diagnosis of distemper, which in a puppy is pretty much 90% plus fatal, and had I made it to the office with her still alive it would have been pretty obvious there service was justified.)

This is not a place to go to to get rid of a nuance pet, but if you have a pet that is obviously in need of this kind of service (and medical evidence ... which I assume they will help provide if you are willing to pay for tests ... which I had already had available, but had I not they would have done the same tests and I assume I would have to [gladly] pay.)

The doctor on site was also helpful in guiding us through the disinfection process for the isolated room we kept her in (as we have our own dogs, and while they were vaccinated against distemper it is not always 100% effective) which consisted of a lot of bleach & water and not to let the other dogs in that room for 2 months!!)
