Ohh she is really turning into quite a beauty! She looks so flirtatious in the picture on the left-hand side, it gave me quite a giggle. I'm very excited for the stacked shot!
As for me, I tend to prefer the cropped look. I do think that boxers with uncropped ears are quite charming as well, and those floppy ears lend to the goofy side of their personality. Cropped ears tend to lend a sharper more elegant look to the animal's head. But really it just comes down to personal opinion- either way it's a great looking breed.
