Kajin
Boxer Pal
My puppies seemed to be very skinny as well. Diesel was 36lbs at 6 months, Kajin was a little more but he was much taller. I don't think there is anything wrong as long as the baby is eating and otherwise is healthy. Kajin was so skinny we were scared to look at his ribs hehe. He was eating a lot though (we switched to adult food at 4 months) and we just decided to wait. He is gaining more weight now as he sort of reached his height.
Try not to worry - everything will be fine.
