Please remember that many factors are beyond our control! Mother nature ultimately calls the shots, so the timing of heat cycles and estimated due date/go-home date may not always be as predicted. Olive & Co. Boston Terriers reserves the right to use a different stud if necessary for any particular breeding. In the event, we replace a stud, Olive & Co. Boston Terriers reserves the first right to retain breeding-quality puppies for our breeding program. Take note that some coat colors may darken over time.
