I just received a call from the vet's office and the vet said that because it has been six days and NO change in the culture, that it is most likely NOT going to change, but we need to wait the full 10 days to make it official. He also said that because we can pretty much conclude that it is negative and we got the negative PCR, that I can reduce the dips to once a week or discontinue completely (at my own risk). I am going to drop to once a week, as it is so very difficult to do the mid-week dip. I have been off of work the past two weeks because I'm a teacher, but we go back to work on Monday. It was so hard to get home late on Wednesday and squeeze in that dip before dinner for my kids, etc. I feel so relieved!! I am still counting on another negative PCR next Saturday and two weeks after that before I discontinue the dips completely. I feel like we are on the home stretch, though!!
