Out of curiousity: Most people know that a dog year is about 7 years (but now the internet is telling me this isn't too accurate. o_o; So how long do you think a "beardie year" would be? I've been trying to kinda figure this out, but every website says something different about bearded dragons' lifespan and whatnot. :?
I'd guess that by the fact they can technically breed between 6 months and a year and their average life span is about 12 years that they age a "beardie year" in about 2 to 3 months.
Mind you its a total guess on my part and I stink at math but with such a short life span which is comparable to a dogs life span, plus the puberty being between 6 months and a year it makes logical sense.
