1-some years back I had an unspayed girl that smelled fishy, turned out she had UTI.
Is your baby spayed?
I don't want to scare you but,
2- years back I and another girl not spayed, she smelled fishy, she was 13 y/o, I thought it was UTI like my other girl had , it turned out she had Pyometra, her uterus erupted sending puss through out her body, she died 9 days later.
Just my experience with fishy smelling females.
