Understanding the period of fertility in dogs is important in managing bitches presented as overdue and requiring intervention, as well as evaluating bitches claimed to be whelping prematurely.
4 lip 2023 · Veterinary preventative oversight requires knowledge of normal versus abnormal conditions in the brood bitch during breeding, gestation, and whelping, as well as appropriate interventions when indicated (obstetrics).
To address this hypothesis, we investigated the efficacy of trilostane (TRL), a competitive inhibitor of 3β-HSD, in terminating pregnancy in dogs. Twenty-one dogs between days 30 and 38 of pregnancy were randomly assigned to one of two treatment groups (trilostane (TRL) and aglepristone (AGL)) and an untreated control (CON) group (n = 7 dogs ...
Pregnancy can be diagnosed by manual palpation of discrete uterine enlargements between Day 20 and 35; by ultrasound after Day 25; and by radiography after Day 46. Fetal heart rate (average around 230 bpm) can be monitored readily by ultrasound, beginning at Day 28.
New and traditional techniques for pregnancy diagnosis in the dog are reviewed. Imaging techniques yield the most information, with ultrasonography the preferred technique for assessment of fetal viability and radiography the preferred technique for assessment of litter size.
Breeding should be timed and managed using vaginal cytology, vaginoscopy, and progesterone to determine luteinizing hormone surge, ovulation date, fertile period, and estimated whelping date. Insemination options include: 1. Whitacre MD, Yates DJ, VanCamp SD, Meuten DJ. Detection of intravaginal spermatozoa after natural mating in the bitch.
