SIck Bearded Dragon (vitticeps)

Question
Hi Pam, My bearded dragon, Dino, is 6 months old and has been in great health until now. I am not sure whether Dino has begun to brumate or is feeling ill (i'll be making an appointment to see the vet tomorrow). Dino has been a big eater and usually eats medium crickets twice a day during periods of about 10 minutes, plus bok choy. Two days ago Dino stopped eating and became very slow and sleepy during the day which I attributed it to brumation because the temp has dropped a lot here (winter in Australia). But today I found vomit next to Dinos head and also passed a solid stool today. Is this usual brumation behaviour? Thank you.

Answer
 Six months old is too young for brumation.  A healthy beardie his age may slow but he should not go into full brumation until he's an adult.  Vomit is never a good sign so it's great you are taking him to a vet.  
 I would also suggest that after a clean bill of health to give him more variety in food.  Have you collard greens in Australia, also known as spring greens?  Turnip tops? Mustard greens?  Dandelion greens?  Rocket or arugula?  These are high calcium greens which are very good for him.  Check with herpetologists such as Dr. Richard Wells in regards to native greens that beardies eat since you are lucky enough to live in beardie home world.  It would save you a fortune to just go foraging for the same weed and plants they would eat in the wild.
