GizzieChewy - what weight is your pregnant female normally ?
Just wondering as mine is day41, and she is small too. This is her first litter, and I think she only has 1 larger and possibly 1 smaller pup.
I know how you feel, but thankfully Tammy is not big so far - she is more wide, than balloon-like. (see pics of pregnant Tammy taken last few days.)
