Hi ya Rachel,
Don't fret Milo was a heavier when he was younger and by the time he got to 14 months, he was as trim as anything, too trim actually, now is a nice weight for his height.
I know Barney's dad was exactly like Milo weight wise, heavier then trim and is now a perfect weight, so don't worry, its in his genes
!! Actually Milo and Chucky are quite similar all round although Milo is a taller dog than Barneys dad.
