What would be sufficient evidence?

It just is not possible to present foolproof credentials on an online forum, especially when anything digitally produced can be faked with relative ease. Even if you put a phone number to your office it could be a scam like the bank account identity theives too often get away with.

Try to bear in mind that a sizeable number of people here are very young and will vote 'best answer' for the one they feel to be the most 'cool' or conformative to the mores of their peer group. Likewise they will TD anything they feel is 'uncool like telling them to grow up. Then there will be trolls and other fantasists; it's just part of internet forum life.

Good answers are always appreciated by others even if the asker doesn't get it.

One problem though, is that with dire symptoms being described, the only sensible answer is to to advise them to go immediately to an emergency vet because the problem could be x, y or z.

Aw Dale, I know how you feel. I research my answers and never answer with anything I don't know to be the truth and very accurate. But much to my dismay, the asker usually chooses some half-baked answer that doesn't even make sense. I think there are a lot of trolls here that just come to make fun of people and harass them. If you told me you were a vet, I'd believe you. Why would you lie? Besides, I'm intelligent enough to know the difference between a good answer and a bunch of bull. We appreciate you and are fortunate to benefit from your knowledge. Just add that you're a vet, many of us will believe you.

"what evidence would be enough to convince you?"

Why do you feel the need to convince anyone?

As Lizzie said, we've had many people claim to be vets. With most of them, if you check their questions, you find out they are teenagers. People can say anything online. And as you must realize, the trouble with someone's claiming to be a vet when they AREN'T could mean that the Asker of that particular question thinks he can believe that answer--when in fact that answer could be dead wrong and possibly cost the life of the dog.

Further, I've known a few vets who have given terrible advice (to me and to people I trust to tell me the truth). So even if you are a vet, nobody's perfect. None of us on this forum are perfect but we try to give the best advice we can.

I see you get upset when you've gotten TD's: https://ca.answers.yahoo.com/question/index?qid=20...

ALL of us get TD's. Even on the occasions when our answers are correct with no wiggle-room to argue. An example: a few months ago a poster who popped up on several questions about rabies claiming humans couldn't contract that virus. Of course he was dead wrong. But when I refuted his claim I got TD's, sometimes more than one, even when I posted links from CDC and other reliable sources proving my point. Go figure. Trolls and other "fans".

In conclusion: post here when and if you feel like it, but for your own sake lose the thin skin. If people TD you or don't believe you're a vet, so what? Don't let it bother you.

I've seen your answers and I believe you are a vet. I also see kids on here claiming to be vets and vet techs. But you, I believe, are a vet. Your answers are what have convinced me. I also believe it is plausible that a vet would visit this site at times.

Don't you worry that giving advice without an examination would open you up to a mal-practice suit? That would be my concern if you indeed are a vet and are dispensing advice in that capacity.

In most locations there is a huge legal difference between offering free advice without examining the animal as a layman and as a board-certified veterinarian. I would cease and desist before you lose your license. That is my major concern with those who say they are "vets" - either they are ignorant of standard practice (in that case, what else do they not know?) or they are lying, 99% of the time.

Give a solid answer if you feel compelled to do so - but DO NOT claim your professional certifications unless you want to lose your license.

We have had so very many wannabe vets in the past that it is hard to believe anyone who claims to be one.

I'm a vet ,, I can even show you my dog tags .. and DD-214
