My frog El Capitan

Hmm... Based on that first pic I'm gunna guess male, head looks pretty wide. But I very well could be wrong, he is young still. Another month or so and I should know for sure.

looks a girl to me it is kinda hard to judge based on those pics, on a first one ( last post) is looks male(ish), second ( last post) and especially 3 in a first post looks like a girl, they just have that kinda cuteness about them when older and smaller in comparison to body head.

Most of the pictures look femaleish to me. And at almost 4", if it was a male there should be more head going on. But who knows some frogs are just harder to tell than others and yours is one of them lol.
