Abstract

Proposing that reproductive health is an important component of animal welfare and postulating the hypothesis that the reproductive health of whole mongrel dogs of 5 years or older, independent of their live weight, would present more subclinical alterations, with respect to younger animals. The purpose of this study was to evaluate and characterize some reproductive health parameters in whole mongrel dogs of different live weights and ages, through a reproductive physical examination and ultrasonographic examinations of testicles and prostate. By means of a sampling for convenience and with the consent of their owners, 90 mongrel dogs over 1 year of age were examined, forming six groups with three liveweight categories (<15 kg, 15-25 kg and >25 kg) and two age categories (>1/<5 and >5 years). The evaluation was carried out by means of physical reproductive examination and ultrasonographic examination, recording higher frequencies of testicular anomalies (asymmetry and flaccidity) and higher frequencies of parenchymal alterations, especially heterogeneity and presence of anechoic foci in dogs >5 years, independent of live weight (p<0.05). In the prostatic evaluation, a higher proportion of ecotextural anomalies, lobular asymmetry, irregular glandular contour and presence of anechoic foci were recorded in groups of dogs >5 years (p<0.05). It should be noted that prostatomegaly was observed in 88% of the specimens >5 years and only in 20% of the younger animals, independent of live weight (p<0.05), reaching 54.4% in the total sample.
