The Dogo Argentino (DA) is the first and only breed from Argentina recognized worldwide. Although its morphologic features have been well established, its normal reproductive parameters are not clearly known. The aim of this study was to determine the main DA bitch reproductive parameters. One hundred and forty-nine surveys were obtained from breeders from Córdoba province, Argentina: one for each intact DA bitch from 1 to 14 years old. The DA bitch reached puberty at an average of 8.93 months. The mean duration of vulval bleeding found in this study was 11.11 days. The clinical signs characteristic for proestrous-estrous were vulval edema (89.93%), bleeding during the time of mating (32.21%), holding the tail to the side (95.30%), and docility during mating (85.91%). DA bitches had a whelping rate of 84%. Out of 299 pregnancies, 89.30% exhibited a normal parturition, 6.69% presented dystocia, 2.68% needed Cesarean section, and 1.34% aborted. In conclusion, the reproductive parameters of the DA bitch are similar to those identified for other large breeds. DA often showed a prolonged vulval bleeding longer than proestrus. Its high whelping rate, its low incidence of dystocia, and its good maternal ability define the DA as a good reproductive breed with normal reproductive functions.
阿根廷杜高犬（DA）是阿根廷第一个也是唯一一个在全球范围内被认可的犬种。尽管其形态特征已得到充分确立，但其正常的生殖参数尚不清楚。本研究的目的是确定主要的阿根廷杜高母犬生殖参数。从阿根廷科尔多瓦省的繁殖者那里获得了149份调查问卷：针对每一只1至14岁的未绝育阿根廷杜高母犬各一份。阿根廷杜高母犬平均在8.93个月时达到性成熟。本研究中发现的外阴出血平均持续时间为11.11天。发情前期 - 发情期的特征性临床症状为外阴水肿（89.93%）、交配时出血（32.21%）、将尾巴向一侧翘起（95.30%）以及交配时温顺（85.91%）。阿根廷杜高母犬的产仔率为84%。在299次怀孕中，89.30%正常分娩，6.69%出现难产，2.68%需要剖宫产，1.34%流产。总之，阿根廷杜高母犬的生殖参数与其他大型犬种的相似。阿根廷杜高犬常常出现外阴出血时间延长，超过发情前期。其高产仔率、低难产发生率以及良好的母性能力表明阿根廷杜高犬是一个具有正常生殖功能的良好繁殖犬种。
