Most bearded dragons listed on Kijiji or Facebook Marketplace were loved. The keeper who’s posting them is usually someone who got in over their head — a job change, a landlord who changed the rules, a teenager who moved out and left the lizard behind. Intent isn’t the issue. The problem is that a bearded dragon can look completely fine to someone who doesn’t know the species, while quietly carrying the long-term effects of years of inadequate UVB, a low-grade calcium deficiency, or a parasite load the seller never noticed. By the time visible symptoms show up, the damage is often significant.
At Toronto Reptiles, we’ve handled beardies from dozens of rehoming situations — from animals in pristine health to dragons with severe metabolic bone disease who’d somehow survived on incorrect lighting and a diet of iceberg lettuce. The difference in outcome almost always traces back to how much the buyer knew before committing. A poorly-chosen animal isn’t just an expensive vet bill: it’s months of rehabilitation that the lizard, ideally, shouldn’t have had to go through.
This guide is a practical, species-specific health check for evaluating a bearded dragon before you drive home with one. We’ll go body part by body part, tell you exactly what you’re looking for, and give you the questions to ask before you even leave your house. If you’re unfamiliar with the species itself, our complete guide to bearded dragon care is worth reading first — it provides the context that makes this inspection make sense.
Key Takeaways
- Metabolic bone disease (MBD) is the most common silent problem in rehomed beardies — check the jaw, spine, and limbs before anything else
- Body weight matters more than body length — a thin beardie with good colour is more concerning than a heavyset one with dull scales
- Clear, tracking eyes and a tight, clean vent are two of the strongest basic health indicators you can check quickly
- Yellow or cottage-cheese-like material at the gumline (stomatitis) is a red flag that warrants walking away
- Enclosure conditions tell the story the animal can’t — a UVI-strip or visible arcadia T5 is a better sign than anything the seller says about their lighting
- If the animal smells like ammonia or the enclosure is consistently damp, substrate health is poor — respiratory infection is a real possibility
Before You Go: Questions to Ask the Seller First
A quick message exchange before you commit to a visit can save you an hour of driving and a difficult conversation on someone’s doorstep. Ask these questions and pay attention not just to the answers, but to how confidently the seller responds. Someone who’s been keeping this animal correctly will usually answer without hesitation.
- How old is the animal, and how long have you had it? Verify that the timeline makes sense. A “4-year-old” that the seller has only had for six months means a stranger’s care history applies to most of its life.
- What does it weigh? An adult beardie (18+ months) should weigh between 300–500g. Anything under 280g in an adult warrants follow-up questions about feeding history.
- What UVB bulb are you using, and when was it last replaced? The correct answer is a T5 HO bulb from Arcadia or Reptisun (10.0 or 12%), replaced every 6–12 months. Compact coil bulbs are incorrect. Reptiglo, Zoo Med mini compacts, or no UVB at all are major red flags.
- What’s the feeding schedule, and what feeders do you use? Adults should be eating collard greens, dandelion, mustard greens, and occasional feeders — not a diet of mealworms and iceberg lettuce. Ask for the last three weeks’ diet if you can.
- Has it seen a vet, and is there any documentation? Even one vet visit on record is a good sign. No vet visits in 4+ years isn’t automatically disqualifying, but it means you’re flying blind on any internal health issues.
- Can you send a recent photo of the full enclosure? Not just the animal — the whole setup, including the lighting strip. You can often spot a coil bulb, an incorrect substrate, or a dangerously small tank from one photo.
If the seller can’t answer UVB and diet questions specifically, that tells you a lot. Vague answers like “regular reptile light from PetSmart” or “it eats anything” signal that care has been improvised rather than researched.
The On-Doorstep Health Inspection
When you arrive, ask to hold the animal yourself before agreeing to anything. A healthy beardie is alert and will react to your presence — turning its head, flattening or puffing slightly, and actively exploring your hand. Watch it for 5–10 minutes before making any decisions.
Body Condition and Weight
Run your thumb gently along the spine from neck to base of tail. The vertebrae should not be sharply palpable. If you can feel individual vertebrae prominently, the animal is underweight or has lost significant muscle mass. Look at the tail base from above: a healthy beardie has width and fat reserves visible at the base. A bony, narrow tail base — like a carrot that narrows too quickly — indicates nutritional deficiency.
The hips are another quick check. Stand the animal on a flat surface and look from behind. If the hip bones are prominent and the area between them looks sunken rather than round and full, that’s a malnourished animal. A healthy weight in an adult is 300–500g (700–1,100g for particularly large males). If the seller doesn’t own a scale, that’s telling in itself — keepers who weigh regularly tend to be the keepers who actually monitor health.
Eyes — Alert, Clear, and Tracking
Bearded dragon eyes should be fully open, clear, and visibly tracking movement. Sunken eyes are a sign of dehydration. Cloudy or hazy eyes outside of a shed cycle can indicate systemic illness. Swollen eyelids or mucus around the eye sockets are concerning and warrant a vet check before you commit to taking the animal.
During your inspection, move your hand slowly near the animal’s face. A healthy beardie tracks this movement. A dragon that doesn’t respond, keeps its eyes half-closed, or appears to be fighting to stay alert is lethargic — which is normal post-brumation, but concerning at room temperature in an active season.
Mouth and Gumline — Stomatitis Check
Gently hold the animal’s head from behind and use your thumb to open the jaw slightly (beardies are generally tolerant of this). The inside of the mouth should be pink and clean, the saliva clear. Look at the gumline along both the upper and lower jaw. If you see yellow, cottage-cheese-like material, or dark, stringy discharge anywhere in the mouth cavity, that’s stomatitis — bacterial mouth rot. It’s treatable but requires antibiotic intervention, and it signals that the animal’s immune system has been compromised, often by inadequate temperatures or humidity.
Also check the lip edges for scale damage, bite marks, or swelling. A beardie that has been repeatedly biting at glass or housed with another beardie may have damaged lip tissue that’s at risk of infection. This isn’t automatically disqualifying, but document it and factor it into your decision.
Vent and Cloaca
Flip the animal gently so you can look at the underside near the base of the tail. The vent (cloaca) should be clean and closed, with no swelling, discharge, or crusted matter around it. Prolapsed tissue — anything soft and pink protruding from the vent — is a medical emergency. Significant staining or brown crusting around the vent can indicate diarrhea, parasites, or cloacal infection.
In males, also check the hemipenal bulges on either side of the vent. They should be symmetrical. Swelling on one side only, or any sign of discharge from the hemipenal region, is a red flag for hemipenal prolapse or infection.
Limbs and Jaw — The MBD Screening
Metabolic bone disease is, in our experience, the most common hidden condition in rehomed bearded dragons. It develops when an animal doesn’t receive adequate UVB radiation or calcium, impairing its ability to metabolise calcium and leading to progressive skeletal deformity and weakness. By the time you can see it, it’s been developing for months or years.
Here’s what to look for:
- Jaw rubbery or soft: Gently press along the lower jaw with one finger. In a healthy beardie it feels firm and solid. In an MBD-affected animal, it can feel slightly soft or pliable — a sign the bone density has decreased.
- Limb bowing: Look at the front legs from head-on. They should be straight and load-bearing. Bowing outward (in the “frog leg” pattern) or obvious curvature is MBD-related deformity.
- Tremors or spasms: Set the animal on a flat surface and watch it walk. A dragon that trembles, collapses, or has difficulty bearing its own weight has advanced MBD and needs veterinary attention immediately.
- Kinked or curved spine: Run a finger along the backbone from neck to pelvis. It should be straight. Lateral curves, S-bends, or a prominent hump mid-back are skeletal deformities associated with chronic UVB/calcium deficiency.
Mild early-stage MBD in a young animal can sometimes be fully reversed with correct UVB, diet, and supplementation — but it requires commitment and ideally a vet visit. Severe MBD in an older animal is manageable but rarely fully corrected. Be honest with yourself about what you’re able to take on.
Skin Condition and Current Shed
Bearded dragons should have smooth, intact scales. Look for patches of stuck shed, particularly around toes and tail tip. Retained shed on digits can cut off circulation and lead to toe loss over time — it’s not uncommon in animals kept in enclosures that are too dry. Check each toe. Also look at the tail tip: if the last few centimetres look pinched, darker than the rest of the tail, or have a ring of stuck shed, that tissue may be at risk.
Normal shed in progress is fine — the skin will look dull and the animal may be a bit less alert than usual. Patchy retained shed from previous cycles, especially multiple layers of it, indicates that husbandry conditions (usually humidity or bath schedule) haven’t been right for a while.
Enclosure Conditions Tell the Real Story
You learn more from five minutes in the room than you do from anything a seller tells you. Before you look at the animal, scan the enclosure. Here’s a quick reference:
| What You’re Looking At | Good Sign | Red Flag |
|---|---|---|
| UVB lighting | T5 HO Arcadia 12% or Reptisun 10.0 on a linear strip | Compact coil bulb, no UVB label visible, “regular reptile light” |
| Basking surface temperature | Seller has a digital gun, shows 40–45°C (105–115°F) | No thermometer present, “it feels warm” |
| Cool side temperature | 24–27°C (75–80°F) range | Single hot rock, whole enclosure uniformly hot or cold |
| Substrate | Tiles, shelf liner, reptile carpet, or bioactive mix | Loose sand, calci-sand, reptile “desert” loose substrate for juvenile |
| Enclosure size | 120×60cm (4×2 ft) minimum for adult | 20-gallon tank for an adult, aquarium not designed for heat gradient |
| Water and food | Fresh greens visible, shallow water dish, clean | Shrivelled lettuce, no water dish, insect carcasses on substrate |
| Faeces | Dark, firm, with white urate | Watery, orange, or bloody stool visible |
The enclosure audit gives you an independent, physical record of the care this animal has received. A seller can say “I’ve always used proper lighting” — the enclosure either confirms that or it doesn’t.
Health Red Flags — Walk Away If You See These
Some conditions are manageable if you’re prepared for them. Others are serious enough that you should decline the animal unless you are specifically equipped for rehabilitation and have a reptile vet already lined up. Be honest with yourself before committing.
- Visible stomatitis (mouth rot) — yellow or cottage-cheese discharge in the mouth cavity. Requires antibiotics and often a vet flush. Not a beginner project.
- Prolapsed tissue at the vent — immediate veterinary emergency. Do not transport a prolapsed animal without a vet involved.
- Inability to bear weight or sustained tremors — advanced MBD. The animal is in active physiological distress. Walk away unless you can go directly to a vet.
- Bloody or watery stool visible in the enclosure — possible parasitic infection, internal bleeding, or severe gastrointestinal issue.
- Laboured, wheezy, or open-mouth breathing at rest — respiratory infection. Requires antibiotic treatment and a vet consult.
- Swollen, discoloured, or obviously deformed joints — possible gout or advanced MBD with joint involvement.
A seller who genuinely cares about their animal should be relieved to hear these concerns, not defensive about them. If someone pushes back hard when you raise health questions, that’s relevant information too.
Transport Home — The First Two Hours
Transport is stressful for bearded dragons. Keep the trip home as calm as possible.
- Bring a fabric pillowcase or a ventilated plastic container lined with paper towel — not a cardboard box, which can collapse and is hard to breathe through.
- Keep the car warm — 24–28°C (75–82°F) ambient temperature during transport. Don’t blast air conditioning on the container.
- Drive directly home — no stops. Every extra 30 minutes compounds the stress load on an animal that is already in an unfamiliar environment.
- Set up the enclosure before you go — have the basking light on and the correct temperatures already established when you arrive home. Your new dragon should be able to warm up and decompress immediately.
- Do not handle for 48–72 hours after arrival. Let the animal settle in, establish its basking rhythm, and eat before you begin building trust.
A vet checkup within two weeks of acquisition is worth doing regardless of how healthy the animal appears. A fecal float and basic exam can catch parasites that are invisible to the eye and don’t always produce obvious symptoms until the load is significant.

Consider Adopting Instead
We’d be doing you a disservice if we didn’t mention this: adopting a bearded dragon through a rescue is often a genuinely better option than buying privately, and not just for ethical reasons. At Toronto Reptiles, every animal in our adoption program has been assessed by us personally. We know their feeding history, we’ve watched their behaviour over weeks, and we know whether they have any health issues going in. When we place an animal, we can tell you about it with confidence.
Private rehoming is sometimes perfectly fine — we’re not saying don’t do it. But the inspection framework in this guide exists precisely because private rehoming comes without those guarantees. If you’d rather skip the uncertainty, see who’s looking for a home — we update our adoptables regularly.
If you’re a keeper who can no longer care for a bearded dragon, you can also submit a surrender request. We understand that life changes — surrendering an animal to a rescue that will genuinely care for it is the right decision.
Frequently Asked Questions
What weight should a healthy adult bearded dragon be?
A healthy adult bearded dragon typically weighs between 300–500g, with larger males sometimes reaching 600–700g. Under 280g in a fully-grown adult (18+ months) suggests nutritional deficiency and warrants a vet visit. Weight alone doesn’t tell the whole story — body condition (spine palpability, tail base width, hip prominence) matters as much as the number on the scale.
How do I tell if a bearded dragon has MBD?
Early MBD is difficult to detect without knowing what to feel for. Signs include a soft or pliable jaw (rather than firm bone), subtle bowing of the front legs, mild tremors when the animal is stressed or active, and difficulty bearing its own weight on a flat surface. Advanced MBD presents as obvious limb deformity, kinked spine, and the inability to walk normally. Any suspicion of MBD warrants an X-ray from a reptile vet, as bone density loss shows clearly on film even when not yet visible externally.
Is it safe to buy a bearded dragon from Kijiji?
It depends entirely on the individual situation. Many legitimate and responsible keepers rehome on Kijiji. The risk is that you have no way to verify care history beyond what the seller tells you. This guide’s inspection framework is designed for exactly that situation — it gives you a physical audit that is independent of what the seller says. Use our guide to buying reptiles safely in Ontario for a broader overview of what to look for across all platforms and species.
Can I quarantine a new bearded dragon with my existing one?
No. Any new reptile should be quarantined in a completely separate room for a minimum of 30 days — 60–90 is better. Bearded dragons can carry parasites and bacteria that show no obvious symptoms but can devastate an established collection. Use separate tools, separate hand-washing protocols, and clean up the quarantine space before going near your established animals.
What is mouth rot and how serious is it?
Stomatitis (mouth rot) is a bacterial infection of the oral cavity. It presents as yellow or cottage-cheese-like material along the gumline, often with associated swelling or discolouration of the gum tissue. It’s treatable with antibiotics and irrigation, but it requires veterinary intervention — don’t attempt to clean it with hydrogen peroxide or saltwater at home. Left untreated, it progresses into the bone and bloodstream. In an otherwise healthy animal, a mild case of stomatitis is manageable; in an immunocompromised animal, it’s a serious concern.
Do I need a vet visit after acquiring a rehomed beardie?
Yes, we’d strongly recommend one within the first two weeks. A basic exam and fecal float will catch intestinal parasites (which are very common in rehomed animals) before they become a clinical problem. If the animal shows any of the red flags in this guide, go directly to a reptile vet — don’t wait for the standard two-week window.
How long does it take a rehomed beardie to settle in?
Most bearded dragons take 2–4 weeks to establish a new routine in a new enclosure. During this time, they may refuse food, stay hidden, glass surf (run back and forth along the enclosure front), or be less responsive than usual. All of this is normal adjustment behaviour. The key is stable temperatures, a consistent light schedule, and not over-handling during the first two weeks. Once the animal is eating and basking reliably, it’s settling in.
