Bitches can suffer stress incontinence when spayed. If kept entire they can suffer potentially fatal pyometra. Bitches get urine infections, i.e. cystitis - I looked after one which I thought was in season but the owner told me on her return
.......... had I known I would have got the Vet. to have a look ......... Bitches can suffer false pregnancy.
They can also suffer mites in their ears or typically 'grass seeds' down the ear canal
......... so they can have similar symptoms ;-)
All mammmals clean their personal places ............. have you not watched male chimps
