Long term under cover at Suvarnabhumi is safe and quite reasonably priced for a 2 week trip.
Just don't do what I did..... Left LOS in February 2020, and couldn't re-enter until October 2020. Long term parking fee - 62,000 Baht!!
I am not sure about some of the advice you are receiving here. I am not sure of the relevance of a 'real time PCR test' or SNAP Test.
If your dog is anaemic , or has a clotting disorder or low platelet count - this will be determined by a Haemogram and Clotting tests.
I would suggest that you don't go to a Vet Clinic & suggest to the Professional which tests he should perform! Nobody likes to be told how to do their job! 555
Also - suggesting the wrong diagnostic procedures will only make you look like a monkey .
Good luck ????
