Gender of these pups ?

Even with this easy method watching them I really can't tell.

So I'd like to gather reactions as many as possible.

Please leave your opinion, if you're (very) sure.

Sorry, I can never really tell from images like that - just the way my brain works (or doesn't obvs).

A great way is to make sure you wake them up when they are all in a pile (or turn the heating up). Little boys use their little bum-cushions to help cool themselves back down - so they are much more visible when they are overheating - especially after sleeping under a gerbil-tower.
