I AM A FEW WEEKS away from bring home our male boxer pup Morpheus, we have been fortunate to be able to vist him. WE noticed this early on but thought nothing of it. However, as the time comes for us to take him we just want to make sure that everything is ok. Morpheus holds his rib cage and his tummy up..(i am not the best at explaining) meaning that his stomach area does not hang down like his littermates. So his stomach area is flat on the bottom from his rib cage down as oppose to his littermates who have hanging tummies. Is this normal.
