as your an old girl you may well have been spayed there should be a scar down
your middle tho its not always visable not much help there
on the musky smell if youve been fixed then it could be adrenal gland problems
not sure how they get to the bottom of this as its difficult to dignose
theres an implant that helps with adrenal issues as well as taking hobs and jills out of season for 18 months to 2 years
