Abstract Characteristics of estrus, mating, and pregnancy were studied in captive fennec foxes. [] Key Result Proestrus, judged by vulval swelling, began 6.5 (±0.7) days before estrus and was not accompanied by sanguineous discharge. Percentage cornified epithelial cells in vaginal smears increased at the time of estrus. In 8 of 10 estrous periods, a single mating followed by an extremely long copulatory lock (mean 1 h 58 min) was observed during continuous video monitoring.
EVIDENCE FOR INDUCED ESTRUS OR OVULATION IN A CANID, THE ISLAND FOX (UROCYON LITTORALIS)
TLDR
The results are the first to provide evidence of induced estrus, perhaps followed by induced ovulation, in a canid species, features that could have selective advantage for this less social, more secretive canid.
THE EFFECT OF THE MALE BUSH DOG (SPEOTHOS VENATICUS) ON THE FEMALE REPRODUCTIVE CYCLE
TLDR
The results from this study can provide managers of captive animals with tools for optimizing breeding potential of this species, including the validation of the noninvasive fecal hormone monitoring technique used.
Presencia de doble estro anual en una hembra de lobo mexicano (Canis lupus baileyi) en cautiverio
TLDR
Results show a significant rise on female sexual steroid hormones concentrations in both, winter and summer, first report in summer of estrus behavior in Mexican wolf.
Hematometra associated with fetal death in a fennec fox (Vulpes zerda)
TLDR
Despite the low blood progesterone concentration and absence of a fetus in the uterus, the histopathological zonary placental findings indicated that the fennec fox had been pregnant.
Geographical Origin, Delayed Implantation, and Induced Ovulation Explain Reproductive Seasonality in the Carnivora
TLDR
It is found that the majority of Carnivora species retained the birth seasonality displayed in the wild, but there was no evidence of an absolute photoperiodic signal for the timing of mating or conception.
Factors associated with uterine endometrial hyperplasia and pyometra in wild canids: implications for fertility.
TLDR
The prevalence of both pyometra and endometrial hyperplasia was associated not only with treatment with the two most common contraceptives but also with the number of years barren (i.e., not producing a litter and not contracepted).
Endocrine and paracrine controls of canine follicular development and function.
TLDR
This review highlights current knowledge on canid reproduction with emphasis on endocrine and paracrine controls of follicular development and discusses future research priorities, including advancing the understanding of anoestrous termination and role ofParacrine factors in canine folliculogenesis.
Canid Reproductive Biology: Norm and Unique Aspects in Strategies and Mechanisms
TLDR
This review summarizes the current knowledge of canid reproduction, including estrus cyclicity, seasonality, and seminal traits, with the emphasis on species diversity.

The estrous cycle in coyotes (Canis latrans) is characterized by a long proestrus (2-3 months). Vaginal smear patterns associated with proestrus, estrus, and metestrus are described. Data from 41

The estrous cycle of 10 intact female wolves, aged 8 months-8 years at the initiation of the study, was characterized in terms of vaginal smears, behavioral observations and serum concentrations of
Reproduction of the Indian wild dog (Cuon alpinus) in captivity
TLDR
The reproductive behavior and development of 3 wild-caught and 2 captive-born dholes (Cuon alpinus) was observed at the Arignar Anna Zoological Park during 4 successive mating seasons and showed the copulatory tie and back-to-back copulatory posture that is typical of other canids.
Photoperiodic regulation of reproduction in the male silver fox (Vulpes vulpes).
TLDR
There was no significant difference in LH release in response to GnRH stimulation in June, but testosterone response to LH release was significantly higher in animals subjected to a restricted photoperiod, demonstrating that testicular testosterone production was maintained longer than in control animals.
Canid Reproductive Biology: an Integration of Proximate Mechanisms and Ultimate Causes'
TLDR
The adaptive value, or ultimate cause, of this reproductive system is most obvious for the more social canid species, such as the gray wolf, where advantages to sociality may have driven development of the anomalies of the reproductive system.
Reproductive features in the female raccoon dog (Nyctereutes procyonoides).
TLDR
More information about the oestrous cycle and gestation in the raccoon dog is needed for adapting this naturally monogamous species to the polygamous mating used in the fur industry.
Temporal relationships between hormonal concentrations and the electrical resistance of the vaginal tract of blue foxes (Alopex lagopus) at pro-oestrus and oestrus.
TLDR
The electrical resistance of the vaginal tract increased rapidly during the last 2-3 days of pro-oestrus, reaching a maximum value approximately 2 days after the oestradiol-17 beta peak that corresponded with the onset of sexual receptivity towards the end of oestrus.
The ovarian cycle of the bitch: plasma estrogen, LH and progesterone.
TLDR
The results suggest that plasma estrogen initiates or potentiates the preovulatory release of progesterone may encourage the LH peak surge and the onset of behavioral estrus and that mechanisms exist that maintain elevated levels of plasma progestersone throughout pregnancy.
Oestrogen and progesterone concentrations in peripheral blood in pregnant red foxes (Vulpes vulpes).
TLDR
Oestrogen levels were low during most of gestation, but there was a significant increase (P less than 0.05) in oestradiol concentrations at implantation and there was no difference in the length of progesterone secretion between pregnant and non-pregnant females.
