This was an interesting article about a veterinarian who was suspended in Maryland. I think most vets in Singapore do a great job - but it's always good to have some sense of accountability. Should one encounter a vet who is negligent or callous, it would be good to have some recourse. I thought that it was a good idea to have a vet licensing body whom clients could complain to, and that there are certain ground rules. Of course, I am sure this body would investigate and be fair to both sides - clients and vets.
Currently, from what I understand the Singapore Veterinary Authority cannot censure a vet - and licensing is done by the AVA.
I think it would be good to have some guidelines on what clients can expect, and also allow clients some recourse without necessarily having to take a vet to court in case of negligence. It also helps that some things are spelt out in the Maryland rules - for example, that a vet cannot deny you a prescription that is necessary to buy medicines at a cheaper rate. I think that right now in Singapore there is a bit of a grey area with many of these issues.
