Sorry if my post sounded awful bex, I meant that the vet should have told you how to worm your other animals at home. I had two very ill barbata that I took to the Vet. One died before I got it there and the other, like you, was eauthanised by the vet and a post mortem conducted. He found worms and promptly booked MOTH in to show him how to worm all our reptiles. I might add, He eauthanised our baby for free and he didn't charge us for the worming lesson either. All we paid for was the crop needle. He gave us syringes and tubes and told us where to buy Panacur from cheaper than what he sells it. This showed me he was more interested in our animals welfare than getting money out of us, which I would have gladly paid him. We bought Panacur (a sheep wormer) from the local produce and went on to worm all of our animals and even the other barbata, which would definately have had the worms, are all doing fantastic.
If I remember correctly, the dosage was 1 milligram Panacur, per 100 grams of weight. But I would check on that, I could be out being as dippy as I am. We used a paper clip to pry open their mouths while poking the crop needle down into the lizards belly and injecting the panacur straight in. To worm the hatchlings we were given a tiny tube to use as the crop needle was too big. You can also inject this stuff into a pinky and just feed the pinky to them but since ours was a serious infection we went with the needles. We were advised to worm all our reptiles every six months as it can't harm them and will keep any intestinal parasites at bay. The same stuff is used to worm the snakes, by injecting it into their meals.
I have talked with this vet and he is willing to check, worm and sex every reptile we will be selling at our shop. Even providing the medical on paper for us to pass on to the buyer.
I do know what you saw and how you felt Bex. I know it's a terrile thing. I cried for ages. I just think you should find another Vet.
