I know that in my poodles and poms it last 3 weeks first week no bleeding lots of whinning 2nd week blood, 3rd week buts in the air ready to mate. No males during that 3rd week for my girls. My males go to the back yard for most of the cycle but for sure that 3rd week.Im not a breeder just a pet lover so hopefully on of the breeders can better assist you. Good Luck |
