I get the reverse from some people, but stemming from the same kind of misunderstanding. My male AM Bully isn't conditioned, but he's in general good shape, the right weight...and I've got to say, he looks great walking with his shiny black coat and muscles rippling.
But, even some ' dog people' offer that he's 'fat'.
I explain, he's not fat, he's an AM Bully, very broad chest, heavier boned than the avg dog...I point out his tuck and waist...no loose skin, show that there's no excess fat on his flanks because his ribs are right there...but it never makes an impression, the same people will say again, nice dog, but he's fat.
