hehe... he still has an athletic look, needs to "fill in the blanks" lol Plenty space for adding some m/mass.. one year from now he will likely look very "serious". Looking at these more recent images, I would say he has now passed the "funny look" stage. I like the black / tan percentage...
I look at all the pictures and I note the deep chest. I am presuming all pups in the litter will inherit that, Axa has a deep one but goodness does the sire have one too lol
