not something ive used ...........
i have tried the idexx test however the bitch missed and it appears different stud owners feel it should read different levels for when to mate
this mating game can be a total nighmere from now on im not premating or idex testing or swabbing any bitch i own if im mating it to a dog i own! instead im listening to my boys and seeing what happens from there!
admittedly if you mate a few days then you have a longer due date but the vets can now take a small amount of blood and tell you if the bitch will whelp in 24 or 48 hours or to re test.... help when deciding to go in for a section i suppose ( this is not something i have done but a friend in the breed has done a few times with sucess)
