Vaginal cytology allows the detection of the estrous cycle phase and reproductive disorders in bitches. The objective of the study was to perform the use of vaginal cytology to detect the estrous cycle phase in female dogs (Canis lupus familiaris) in the city of Belém, Pará State, Brazil. The vaginal cytological exams were previously authorized by the guardians, being carried out in 23 female dogs, without defined breed (SRD), with age between 6 months and 14 years, weighting from 5 to 25 kg, before being submitted to ovariosalpingohysterectomy (OSH). The results showed that 13.04% (3/23) of the females were in proestrus; 21.73% (5/23) in estrus; 39.13% (9/23) in diestrus and 26.08% (6/23) in anestrus. Thus, it was demonstrated that vaginal cytology can be used in the clinical routine of canine females for diagnosis of the estrous cycle phase, emphasizing that the association with clinical and hormonal evaluation favors greater accuracy in this diagnosis. La citología vaginal permite detectar la fase del ciclo estral y los trastornos reproductivos en las perras. El objetivo del estudio fue realizar el uso de la citología vaginal para detectar la fase del ciclo estral en perras (Canis lupus familiaris) en la ciudad de Belém, Estado de Pará, Brasil. Los exámenes citológicos vaginales fueron previamente autorizados por los tutores, siendo realizados en 23 perras, sin raza definida (SRD), con edad entre 6 meses y 14 años, con peso de 5 a 25 kg, antes de ser sometidas a ovariosalpingohisterectomía (OSH). Los resultados mostraron que el 13,04% (3/23) de las hembras estaban en proestro; el 21,73% (5/23) en estro; el 39,13% (9/23) en diestro y el 26,08% (6/23) en anestro. Así, se demostró que la citología vaginal puede ser utilizada en la rutina clínica de las hembras caninas para el diagnóstico de la fase del ciclo estral, destacando que la asociación con la evaluación clínica y hormonal favorece una mayor precisión en este diagnóstico.
