I have a 6 year old bitch that has silent heats. Basically no swelling and very little pinkish fluid by the time she shows anything. Any suggestions on when I should start testing with the progesterone testing? I've got the pre mate kit from Camelot farms and have been to a specialist. The vet tells me i should do a test every week to be able to catch when she comes in. Vet wants to charge 100 a test. This can get quite expensive and she doesn't recommend me using the pre mate kit. Says it's not reliable. Any suggestions will be helpful. Thanks guys

sorry guys I put this in the wrong spot. If the moderaters can move this thread into the canine reproduction section. Thanks
