Bearded dragon walking funny

[Chrisbkr123]

My bearded dragon has been walking funny the past 5ish days. When he goes the start walking he lurches to one side and almost falls over and he has almost stopped using his back legs. He uses them just a little bit. We aren’t sure what to do the only thing we have changed lately is putting a new uvb bulb in cause the last one was kinda old.

Do you by chance have a video of him? He might have metabolic bone disease if he is not using his back legs. You'd have to consult your local vet to see what is the matter.
