Thanks for all of your input. It's unfortunate that it is so difficult to find a knowledgeable reptile vet. This is the most knowledgeable reptile vet in our area. There is one other but apparently he knows even less/has never kept reptiles/has no ties to the reptile community whatsoever

I had brought up all of my concerns regarding the bacteria becoming resistant to the antibiotics, like superbugs in humans. Antibiotics kill some bacteria, if you don't complete the course, the more-resistant strains are left behind, the more resistant strains multiply, therefore making it more difficult to kill and needing a longer, stronger course of antibiotics the next time. He said that's not how it works.

The thing with the Amikacin, I had suggested that drug to him in the very first place, but he said it's not as available in Canada, it's not used very often because it's expensive and expires quickly so they don't like to stock it on their shelves because it doesn't get used up.

Then all of a sudden (I guess maybe he did some reading?) He changed her over to Amikacin. I have read that it's a VERY powerful drug, but he also gave my friends snake Amikacin, and there was about 2cc in his syringes, (about an inch worth of medicine) and we only got about 1/16" worth of medicine in our syringes. So when I was dosing her it seemed like the meds were not even there, it was such a small amount. The snakes were approx the same weight. Don't know what's up with that. I asked him too and all he did was repeat the dose to me in mg/kg and say that it was correct. I'm not sure if he's saying he gave our friends snake an incorrect dosage...?

Yes she is in Quarantine in a completely separate room, it will be very easy to bump up her temps a little more.

And I figured I was also correct about the RI never being cured. Maybe he's never cured an RI then. I don't know. I just don't know what to do. I'm not a vet, I don't have the ability or authority to conduct any of these tests or get my hands on any of these drugs, so what am I supposed to do!?
