This is for those of you who have both male and female boxers, is it normal for their body shapes to be different? Gunnar is very tall and lean, he literally RIPPLES muscles down his legs, his neck, he looks like a boxer on steroids. My little Ginger, she's a little on the chunky side, not FAT now, she's just thicker than he is. And she's not nearly as muscular. Is this typical???
