How can it be so difficult to photograph puppies?

I admire breeders who publish photos of their litters starting when the pups are around 5 weeks old. The pups looks like they are born to pose. But not in our household ...  we might get one or two pics like this:

.. but most photos are like this (or even worse...) :

One of the red boys ... age 5,5 weeks and he seems to be hungry all the time, so treats make this...

The red girl in Finsweng X or Y litter didn't want to cooperate.

Training of the blue boy.

Even if they move nicely and stand nicely when moving around in our living room / garden, the most pups don't pose nicely on the table. And even if my family know how to photograph, it seems that photographing puppies is too hard for us :D  We'll continue training! And photographing and laughing!
