Bearded Dragon dying? Please help...?

Hi. I'm really sorry to hear that and I hope he's ok. If he is ok or if you get another lizard TAKE OUT THE SAND!!!! I cannot express enough that sand is so bad for lizards. If they accidentally consume it, it will clog up their system and cause them to stop eating. Eventually they will start into seizures and sleep a lot. This happened to my lizard once and luckily I took him to the vet in time so he survived. I would really stress that you NEED to see a vet. This can be very serious! I would also keep his heat lamp on all night and heat pad. I really pray for the best for you and I hope this helps!
