The ultrasonic (B‐mode) detection of canine pregnancies was first achieved 21 to 23 days after the calculated luteinising hormone peak when daily examinations were made in six bitches. In 51 pregnant bitches examined for the first time between 20 and 35 days, one bitch was incorrectly diagnosed as non‐pregnant 24 days after the calculated luteinising hormone peak. In only 31‐8 per cent of pregnancies was conceptal number accurately determined. The greatest tendency was to underestimate the number of conceptuses.
