We compare differences in the reproductive strategies of "free-living" dogs with their wild relatives in the genus Canis, of which the dog is a very recently evolved member. The members of this genus display a greater range of parental motor patterns than generally seen in other species of Carnivora, including pair-bonding and extended parental care; parents regurgitate to offspring and provision them with food for months to as long as a year. But the domestic dog does not routinely display… Expand
Genetic inference of the mating system of free-ranging domestic dogs
Abstract Domestication has greatly changed the social and reproductive behavior of dogs relative to that of wild members of the genus Canis, which typically exhibit social monogamy and extendedExpand
The great Indian joint families of free-ranging dogs
A five year-long field based behavioural study on parental care of free-ranging dogs in India reveals the presence of widespread allo-parenting by both adult males and females and provides support for both the “benefit-of-philopatry” and “assured fitness returns” hypotheses. Expand
Canid Reproductive Biology: Norm and Unique Aspects in Strategies and Mechanisms
This review summarizes the current knowledge of canid reproduction, including estrus cyclicity, seasonality, and seminal traits, with the emphasis on species diversity. Expand
Dogs' (Canis lupus familiaris) behavioral adaptations to a human-dominated niche: A review and novel hypothesis
Abstract This chapter contextualizes the dog-human relationship in the dog's origin as a scavenger on the fringes of human settlements over 15,000 years ago. It then reviews the evidence for uniqueExpand
Ontogeny of domestic dogs and the developmental foundations of carnivoran domestication
It is concluded that ontogenetic preconditions as well as body size constrain the species’ capability for artificial selection in domestic dogs and cats and speculate that the human requirements for functional performance of their domesticates might render some developmental biases substantially.

Dogs’ remarkable success in living in a human-dominated world rests on a set of adaptations to cohabitation with humans. In this paper, I review the nature of these adaptations. They include changesExpand
Chapter 1 Introduction to dog behavior
Dog evolutionary history What is a dog? The answer can come in the form of a description of the dog’s characteristic behavior, physical description, or evolutionary history. We will begin with theExpand
Timing of reproduction and association with environmental factors in female free-roaming dogs in southern India.
The prevalence of pregnancy varied by month in both locations indicating seasonality of reproduction in these groups, and environmental factors were associated with patterns of pregnancy in free-roaming dogs, however statistically-significant factors varied by geographical location. Expand

Although common and widespread today throughout the neotropical lowlands, the domestic dog (Canis lupus familiaris) may have been a relatively recent introduction into certain areas. Numerous earlyExpand
Differences in the Behavior of Landraces and Breeds of Dogs
The domestic dog has many phenotypic and behavioral forms. In this chapter we describe five different kinds of dogs and how each has been derived. We trace the background village dog adapting to theExpand


A study of dog-coyote hybrids and implications concerning hybridization in canis.
  • R. Mengel
  • Biology, Medicine
  • Journal of mammalogy
  • 1971
The phase shift in the breeding season of F1 hybrids, requiring the young of animals presumably less fit than coyotes to be reared in midwinter and in the absence of male parental care should form an effective block to the development of hybrid swarms and to the introgression of dog genes into the coyote gene pool.

Cooperation, Altruism, and Restraint in the Reproduction of Carnivores
It is suggested that studies of the processes that direct an animal towards a given reproductive (or social) role would be fruitful, and that they might most usefully be approached in terms of the effects of ecological circumstances on social organization, and on the development of individuals and their social relationships.

This review considers the behavioral, ecological, and reproductive characteristics of mammals exhibiting monogamy, i.e., mating exclusivity. From a discussion of the life histories of selectedExpand
Reproduction in Wild Canids, Canis-Familiaris, From the Eastern Highlands of Victoria
Overall this sample of canids displayed reproductive characteristics, such as a seasonal breeding season, considered typical of dingoes, however the possibility of slight changes to the original dingo breeding patterns through hybridization with domestic dogs is discussed. Expand
The ecology of dogs and canine rabies: a selective review.
In Nepal, Sri Lanka, Switzerland and Tunisia, dogs are poorly supervised and their population densities are high enough to support rabies, although it is questionable whether canine rabies exists independently of a wildlife reservoir. Expand
Early Ontogenetic Diet in Gray Wolves, Canis lupus , of Coastal British Columbia
Examination of faeces deposited by altricial pups and adult providers at two den sites over two years on the central coast of British Columbia, Canada suggests that adults selectively provisioned pups, and speculate that this may relate to adaptive strategies of adult wolves to provide their offspring with food of optimal nutritional value or reduced parasitic burden.

Reproductive Biology of the Coyote (Canis latrans): Integration of Mating Behavior, Reproductive Hormones, and Vaginal Cytology
It was found that patterns of proceptive and receptive behaviors correlated with the secretion of steroid hormones, as did vaginal epithelial cytomorphosis, and key aspects of reproduction were correlated temporally, and the importance of an integrated perspective was emphasized. Expand
The social organization of free-ranging urban dogs. I. Non-estrous social behavior
Familiarity between dogs was the primary basis of sociality, although the distance a dog was from its home-site, its body size, age and ownership status also influenced social behavior, and resources such as food and shelter influenced the social organization by concentrating individuals in areas where these were available.

Causes of Reproductive Failure in Two Family Groups of Wolves (Canis lupus)
Results of this study tentatively suggest that antagonistic relationships may have influenced the hormonal basis for sexual attractivity of females, for copulatory behaviour of males, and for age of first ovulation in wolves. Expand

Abstract Canids and felids are compared regarding evolutionary history, distribution, habitat preferences, morphology and behaviour. Factors permitting and promoting sociality in both families areExpand
