Our vet came by earlier today.
He did an ultrasound on both Daisy and Frieda. They are definitely not pregnant.
Due to Hubba's and my travel schedules we did not follow the complete protocol, so chances are, they were never pregnant.
He gave us a slightly different protocol to follow, so hopefully we will be have better luck next time.
The good news: Kocoa is definitely pregnant. She is due on October 17th. She has been unpredictable for her first two pregnancies, so we will be on official watch starting October 1st, but I'm expecting the cria will arrive closer to Halloween.
