Possibly impacted Bearded Dragon

Question
We moved our 1 year old dragon to a larger cage 1 week ago.  It took a couple days to get the basking area at the correct temperature and get the cage organized correctly.  We also went from reptile carpet to calci-sand for the first time.  Our beardie is over 15 inches long and 13 months old.  He's eating and drinking fine but he hasn't pooped in 1 week.  We removed the calci-sand yesterday and replaced it with reptile carpet.  We've given him two baths a day for the past 2-3 days.  He is acting pretty normal but at what point do we bring him to the vet for a possible impaction?

Answer
 He should see the vet as soon as possible, in the meantime, if you have a clean eyedropper or needleless syringe, try and get him to swallow a few drops of coconut or olive oil.  That may help get things moving.  The baths are good, and a clockwise circular gentle rubbing of his tummy may also help.
