Are there ways to tell if you have a 1 yr old dragon or a 5 yr old dragon or a 7 yr old dragon?
I have asked 2 Vets how old Beast seems to be, one told me he was 1 the other said 5.
Any thoughts?
Not really. Once they reach adult size, there aren't really very many clear cut or distinguishing factors that indicate age. They generally look the same as adults from 1 or 2 years up to 9 or 10 if they've been well cared for. Older beardies get a kind of worn look to them, but that is in no way a sure method of determining age.
You can post up pictures and the forum members can take a shot at guessing the general age, that may help you out.
He does look a little Skinny, but not badly, only like he skipped a few meal's.
But he doesn't look "Rough, Worn Out or Rugged" so I would guess between 1-4 year's old.
