About a week ago, my beardie was puffed up with sand all over his face and in his mouth...the next day we took him to the vet who said he had an infection, gave us antibiotics, and syringes with food to force feed him. We did it for about a week, and then tonight, he threw up and ate more sand. He is puffed up, writhing around and now isn't moving. His feet are cold. He is breathing but barely. He has an appointment tomorrow morning with the vet as a follow up, I just hope he makes it. I have no idea how this happened. Is it the sand? The vet said they eat the sand when they want to make themselves throw up like when dogs eat grass...
