Damn it, I'm so sorry, I was really hoping he would pull through this. You definitely did everything you could do, and this is no one's fault but that vet's. A perfectly healthy, happy dragon was poisoned by a veterinarian for no reason, and you absolutely need to let that vet know how much research you've done about Ivermectin in ANY and ALL reptiles, and let her know how upset you are that she wasn't educated about the medication she gave him. If nothing else you can prevent her from not killing anyone else's reptile...I'm just so sorry, this is so unnecessary and just irresponsible and wrong. And it's one of many, and this needs to stop...
