My new baby bearded dragon!

Question
He has been doing well, up until about 2-3 days ago. He hasn't really been eating, but he still moves around and sun bathes. Just about 20mins ago, I looked over to see him violently shaking his head, causing him to spit up this long brown thing. He has never had meal worms..or and worms..Just the small crickets, and the romaine lettuce. Is it possible he ate to many at one point in time and he was hacking it back up? I don't want 2 have to g tot he vet if I don't need to, since its highly expensive! After doing that he went to lay back down under the light and closed his eyes.

Answer
Hi Tiffany, Beardeds can potentially vomit from ingesting too large a meal. If it can't be properly digested because of the amount or the lack of heat, or both, they may regurgitate it. Make sure your basking temperate is adequate, about 100 to 110 F. The crickets also need to be fairly small for baby beardeds, no longer then the distance between the bearded's eyes. Older, larger crickets have a lot of undigestible portion to their bodies compared to young crickets and can cause digestive problems in young lizards. With baby beardeds I like to feed twice a day so there is less chance of overeating.
Vomiting can also be a sign a a couple more serious conditions like impaction or intestinal parasite infections. Young beardes should not be kept on any type of loose, particle substrate like sand, even the calcium based sands. Paper towel or newspaper is best until they are older to reduce the risk of the substrate causing intestinal impaction. If your baby was kept on a loose substrate by you or before you acquired him there is a risk. You can sometimes help move impactions along by soaking the dragon in a little tepid water which encourages a bowel movement. Gently massaging the belly area and feeding high fibre veg. like squash baby food can also help.
Intestinal parasites, which are very common with beardeds, will really need to be treated by a vet.
