Field notes
The instructions distinguish a mating date from an ovulation date established by a veterinarian, and say that the displayed calculation uses the latter when selected. For several recorded matings, the page recommends keeping separate estimates rather than averaging dates into a presumed conception date. It also compares its planning window with ranges cited from VCA and Merck, while cautioning that a dog outside its own window needs individual assessment.
