I am grateful you posted that pic, even though it hurt my heart to look at.
I just picked up a MBD rescue Wednesday night and while his spine isn't curved, he was unable to walk 3 weeks ago and is now shuffling around his viv. I've only known him for a few days and I cried over him before I ever brought him home. I can't imagine your heartache.
My heart goes out to you and to your little fighter.
The person I got my rescue from said it may have been best to put him in the freezer, but kept him just to see if he could recover. (Sorry about the freezer comment but that is what he said). Considering how far he has come in three weeks, I know he will continue to improve. I wonder what your guy will be like in 3 weeks?!?!?! If mine can go from paralysed hind legs to walking (crippled walking :| ) then yours just
has to be able to improve, too.
I got a lot of amazing advice from Cheryl at beardeddragon.co. She does rescues and has some great ideas regarding liquid calcium and supplements for MBD. She has been very kind to us asking her questions and can make calcium blends to suit your dragon's needs.
Can you keep this thread updated and maybe with pics if there are any changes? Or maybe we could communicate via PM? We have a similar situation going on here between our dragons. I hope every day brings better health to your beardie.
