Studies on the physiology of reproduction in the dog. I. Duration of oestrus


, : Studies on the physiology of reproduction in the dog. I. Duration of oestrus. Japanese Journal of Animal Reproduction 18(4): 132-136

Observations were made on 50 mongrel bitches aged 2-4 yr and weighing approx. 10 kg. 31 bitches were mated during oestrus, of which 23 became pregnant. The duration of pro-oestrus averaged 8.3 days (3-27), the duration of oestrus 10.9 days (5-20) and the duration of pro-oestrus plus oestrus 19.4 days (11-35).
