My Bearded dragon all the sudden is hiding majority of the day and I don't know why! Also he is only going to the bathroom once a week and i found that kind of weird. This is my first beaded dragon and I've had him almost a year now.
Has your dragon ever been to the vet? Parasites maybe. Could be brumation. You need a vet visit and fecal. Also makeep sure your lighting is correct and basking temps.
You need to have a yearly checkup and fecal done at least once a year. Twice a year fecal exam wouldn't hurt. You don't want a dragon to brumate with a heavy parasite load.
