Thank you, guys!
The picture I posted is probably over one month old - he was sick then, i couldn't bath him etc. Here is a newer picture but it's still probably at least 2 weeks old. I'll make his recent pictures in the nearest time - I've just got a new camera and I'm trying to figure out how to use it.

And I completely forgot that yes, whole male loose weight when they start breeding. I remember now my previous stud male was sometimes just skin and bones and was successfull at shows only because of his long fur. Thank you for reminding me that!
