My bearded dragon isn't acting himself...? mk II?

my husband and i used to have a bearded dragon. to us, it sounds like it needs to have a bowel movement. try putting it in shallow, lukewarm water. that is how ours relieved itself. it may also be stressed, since you have not had it that long. if it doesn't have a bowel movement soon, then it may be blocked and you will have to take it to a vet. we kept a water bowl in our cage, but she mostly used it for her toilet. make sure if yours does go in the bowl, change the water soon after. trust me, you will want to because it will stink to high heaven!! i also suggest you buy a book on bearded dragons. before we got ours, we read up alot on them. you have to make sure you have their temperature in their cage just right. don't rely on what the pet store people tell you. they don't know much sometimes. consult with a vet, that specializes in reptiles. there are good books out there for you to read. i wish you good luck. we loved ours very much and miss her terribly.
