Oestrus was characterised in nine German shepherd bitches by measuring plasma levels of luteinising hormone (LH), progesterone (P) and oestradiol‐17ß (O). Hormone concentration data were compared with the eosinophilic index (EI) obtained from exfoliate vaginal cytology. Maximal values of O and LH occurred before the maximal EI value. The EI peak followed the O peak, with a two day delay. LH increased during the first 24 hours after the maximum 0 value, and P levels were then slightly higher than basal.
