The dispersal of free-ranging dogs from Katwa, West Bengal, India, was studied between January 1993 and December 1996. Between January 1993 and September 1996, 315 pups were observed from 64 litters. Pups were born between October and March each year, with a peak between November and January. The mortality rate was 68% during the first 4 months, with 102 individuals surviving to the juvenile stage (4 to 12 months). The rates of dispersal were 39.3 and 23.3% in juveniles and adults, respectively. Mean home range sizes were 4.8+or-1.7 and 8.4+or-1.7 ha for non-dispersing and dispersing dogs, respectively. Moreover, there were significant seasonal variations in the home range sizes of both non-dispersing and dispersing dogs. Juvenile males were the predominant dispersers. Dispersal occurred in all seasons and dispersal rates did not differ between seasons. However, during late monsoon (September to November), dispersal was significantly greater among males than females. The mean dispersal distance of 1.702+or-0.425 km was relatively small, and did not differ between males and females.
