JB or GO?

I had a lot of shots after spending a morning with a friend and her two beautiful dogs and it was very hard to pick up just one. It looks as if they were posing for me but in fact they were playing around like crazy all the time stopping just for a split of a second. Still, I did manage to get a lot of lovely shots. However, I have no idea whether it is GO or JB, they are like twins to me.
