Weed identification for Russian tortoise

[Timmythetort8]

does this weed look safe to feed my Russian tortoise? I think it's prickly lettuce but I could be wrong and just want to make sure.

It's a sow thistle, a lettuce relative. Safe, although I'd let it grow a bit; its not much to eat right yet.
