Treat a bearded dragon that has stopped passing stool as urgent — and as an emergency if the back legs become weak or paralysed, or the belly is hard and swollen. Not pooping usually means impaction: the gut is blocked, often by swallowed substrate (loose sand or small particles), a too-large or hard-shelled feeder insect, or by being kept too cold to digest. Check the husbandry, offer a warm bath, and see a reptile-savvy vet — a severe impaction can press on the spine and is a surgical emergency.
## What impaction is Impaction is a blockage of the gut. Common causes are ingesting loose substrate (sand, walnut shell, small gravel), eating prey that's too large or too tough (a feeder wider than the space between the eyes, or hard-shelled insects), and being kept too cold to digest food. A mass of blocked material can build up and, if severe, press on the nerves to the back legs.
## Signs to watch - No droppings for longer than normal for your dragon (which depends on age and diet). - Straining with no result. - A firm, swollen lower belly, or a visible lump. - Weakness, trembling, or dragging of the back legs — a serious sign the blockage is pressing on the spine. - Loss of appetite and lethargy.
## What to do Check that the basking temperature is correct (a cold dragon can't move its gut) and switch loose substrate for a solid liner. A warm bath (shallow, around 30–35°C / 86–95°F, chest-deep) and gentle belly support can encourage a mild impaction to pass. If there's no result, or the back legs are affected, or the belly is hard, see a reptile-savvy vet promptly — do not give oils or laxatives without veterinary advice.
Get to a vet immediately if you see any of these
- Weakness, trembling, or paralysis of the back legs
- A hard, swollen belly or a visible firm lump
- Straining repeatedly with no droppings and going off food
- No droppings for well beyond the normal interval
- Impaction after eating on loose sand or a too-large insect
Common questions
How often should a bearded dragon poop?
It varies with age and diet — juveniles on lots of insects may go daily, adults every few days. What matters is a change from your dragon's normal pattern, especially with straining, a swollen belly, or loss of appetite.
Why do the back legs go weak with impaction?
A large blocked mass can press on the nerves running to the hind limbs, causing weakness or paralysis. That's a serious sign that turns an impaction into an emergency needing veterinary care.
What substrate is safest?
Solid liners (reptile carpet, tile, or newspaper) avoid the substrate-ingestion that causes many impactions. Loose sand and small particles are a common culprit, especially for juveniles.
