How ageing shows in a dragon
Senior bearded dragons telegraph their age through movement. The vertical dashes up a tall basking branch stop; the dragon chooses the lower, wider ledge, walks flatter, and may hesitate before turning. Eyes can look a little more sunken, muscle along the tail base thins, and brumation in winter often deepens and lengthens. Appetite usually narrows toward favourite foods. None of this calls for panic — it calls for an enclosure and routine redesigned around a lizard whose joints and energy are not what they were at three years old.
Heat, light and easier basking
Heat and UVB remain non-negotiable, but access changes. Bring the basking spot down or build a broad, gently sloped ramp up to it, with a surface that grips ageing toes; a dragon that cannot reach its basking temperature cannot digest properly, and an old dragon will often sit cold rather than climb painfully. Keep the basking area at the usual adult temperature and the cool end available, and replace UVB tubes on schedule even if they still glow — output fades long before the light does, and older bones are the least able to afford weak UVB and the calcium problems that follow.
Food, calcium and weight
An older dragon's plate should lean further into greens and vegetables — the salads it may have spurned as a youngster — with insects offered as quality rather than quantity: gut-loaded, dusted with calcium, and sized for a slower gut. Fatty feeder insects become an occasional treat, because senior dragons gain weight around the organs while losing muscle, a combination that strains the liver and kidneys. Offer water by dripping it on the snout or in shallow baths; many older dragons drink reluctantly, and mild chronic dehydration is one of the quiet drivers of kidney trouble in this species. Weigh monthly and write it down.
When to see the vet
A senior dragon deserves a vet visit for a black beard that stays dark outside any obvious stress, persistent food refusal outside brumation, tremors or weak grip in the limbs, a swollen jaw or limbs, or diarrhoea that does not settle. Stiffness that suddenly worsens can be pain rather than age, and gout — painful swollen joints — is a recognised problem in older dragons that a vet can assess. An annual senior check with bloodwork, where your vet offers it, is money well spent on an animal whose organs are doing their second decade of work.
Old age in a dragon is a trail of small numbers — weights, UVB change dates, appetites across a brumation — and a KinsLe Pet Passport keeps those numbers together in one packet, so each vet visit starts from the full story of how your dragon has actually been.
