Heat Cycle of The Female Dog Estrus

What is Estrus? The stage in which the female is receptive to the male and conception can occur. Duration varies Lasts approximately 3 – 9 days

Clinical Signs of Estrus Less edema Discharge becomes clearer Discharge is more yellowish then bloody

Clinical Signs of Estrus Vulva remains turgid, very warm when touched, and voluminous Female will stand “Flag” for the male

What is Flagging? Female will stand for the male Rear in the air Tail off to the side

The Cytology of Estrus Difficult to determine. Distinguishing features only at beginning and end of the estrus cycle. Influenced mainly by estrogens.

Cytology During Estrus Grandular Secretions increase

Cytology During Estrus Vaginal epithelium becomes hyperemic

Cytology During Estrus Ovulation occurs

Cytology During Estrus Increase in LH Hormone. 90% Superficial cells Bacteria usually present Absence of Neutrophils
