I have heard/read that the AKC will accept/register a litter as long as the female was at least 8 months old at the time of breeding. Never breed on the first heat, second one is okay. Flea medicine (or any other medicines etc) always check with your vet first. Bathing at this point is fine. I was told not to bathe the female for a coupe of days right after breeding; don't quite understand that, but it's what I've heard. Regular exercise/outings are okay up until the last week or so; then it's time to slow her down a bit. These are all things I've been told by my breeder and/or things I have read on the subject (and I've read plenty!). I am a beginner breeder myself. My Lexie just turned 1 yr old yesterday and we are hoping that she is pregnant right now. Sounds like your Koko is about a week or so ahead of Lexie's schedule. If Lexie is pregnant her expected due date will be October 20th. When will Koko be due to deliver. We can compare their pregnancys!
