Abstract

Saliva ferning, a non-invasive and painless technique to time ovulation has been used in humans. A survey of local references showed that none has been done to determine ovulation in dogs, hence this study. A total of 43 paired samples of saliva and vaginal smear from 43 dogs were conveniently sampled. The vaginal smears were assigned to a specific phase of the estrous cycle based on the observed presence of erythrocytes, neutrophils and computed SCI and KPI. The saliva samples were air-dried, examined and graded for the presence of fern-like patterns. Grading was done base on the presence, length and degree of stems, venations and subvenations. Result showed that the saliva ferning pattern grade increases as the animal approaches estrus with a peak observed at the late proestrus. Furthermore, the saliva ferning pattern grade drastically drops at the onset of the early estrus which continues until mid estrus. This pilot study on saliva ferning shows its potential to time ovulation and optimum breeding time like vaginal cytology.
