Grandmotherly care: a case study in Indian free-ranging dogs

Abstract

Parental care is an essential component in the life history of mammals. In group-living species, care can be provided by adults other than the parents, and such care is termed alloparental care. Alloparental care is known in a wide spectrum of species, from insects to humans. Most canids that live in stable packs demonstrate cooperative breeding, where subordinates provide care to the offspring of the dominants, without reproducing themselves. Free-ranging dogs in India have a dynamic social system and, unlike their cooperatively breeding ancestors, the grey wolves, all adults in a dog group have equal mating opportunities. This at times leads to the birth of multiple litters within an existing dog group. In this paper, we report the first field observations of alloparental care made on a dog group where a bitch provided care to her grandpups, through interactions other than suckling. The allomaternal care acted as a supplement to the care provided by the mother, and was thus beneficial to the pups.
