Yes, don't stop posting, it's nice to hear good things for a change! The hornworms are a good idea if she'll eat them, any nutrition you can get in her is going to help her fight the Infection. You did the right thing in dusting the hornworm, repeat if you can. I wish I had a pet store locally that sold them or Phoenix/Reptiworms, all I have within 2 hours of me is a Petco and 2 private pet shops and between all of them I can get crickets, mealworms, wax worms, and superworms. I asked someone at Petco a month ago if they would ever carry hornworms, because I know PetSmart does, and he told me no because they sell "frozen pinky mice" for Beardies as a treat, and they're better than hornworms for them. He was the general manager of the entire Petco. Uhg.
Anyway, I'm assuming she's feeling better due to a combo of the food and fluids and the Baytril finally kicking in, it's a good choice as a broad-spectrum antibiotic. Reptiles heal slowly so it often takes weeks to actually see the effects of the antibiotics. I'd keep trying to feed her what she'll eat, if it's a big hornworm a day then so be it, they're nutritious, if it's a few wax worms a day then so be it, it's nutrition. As you feed her and keep giving her the Pedialyte you should see her gums slowly pink up because of the nutrition from the food. You may not even need to pursue the transfusion if she keeps eating. Others here may disagree with me recommending hornworms, wax worms, etc. but if she's malnourished enough that she needs a blood transfusion due to anemia, then I believe it doesn't matter if what she's eating is fatty. It's a short-term thing and the alternative is, well, you know what the alternative is.
And don't worry about her
drinking a little watered-down Betadine, it's just Iodine, like the kind added to table salt, we all need a little of it in our diets. The small amount she drank was not poisonous, she'd have to drink quite a bit to be seriously harmful. You did the right thing, if she starts
drinking the Betadine water during her soaks just stop her and give her fresh, clean water. Using unflavored Pedialyte is a great idea as well, electrolytes and
hydration are going to help just as much as the nutrition is.
I've stated on here before that in my studies of Animal Health Science throughout college and grad school, and then working at the Animal Diagnostics Lab at Penn State University afterwards, often people are so concerned with "treating" their pets for whatever illness or injury it is they have, they often times forget to force nutrition and
hydration, and then the medical treatments they are giving their pets doesn't work because the animal is too weak, too anemic, too dehydrated, too malnourished for the medical treatments to have a chance to work. And this doesn't just apply to the pet owners, but their veterinarians as well. How often do you see veterinarians giving a sick dog IV fluids or nutrition before sending them home? Sick or injured pets don't often stay overnight in animal hospitals, either due to financial reasons or just because it's deemed unnecessary. Sick or injured people however are very often admitted into the hospital, either overnight or at least into the ER for a number of hours. And the very first thing that is done in the ER is an IV is put in and a fluid solution like Lactated Ringers is administered. It's just the protocol. So why don't we treat sick or injured animals the same way? I've often told people on here to "Force Feed" or "Force Fluids" to their Beardies and I've had others tell me I'm wrong because it will stress the beardie out, and it's okay if they lose a little weight. Well I'm not telling them to force nutrition and fluids because of weight loss, but because if a bearded dragon is seriously ill and hasn't eaten in days and is dehydrated, how are their bodies supposed to fight off an infection?
