The bush dog experiences several developmental stages, beginning with the “Embryo” stage where the fetus develops within the mother. The young are born blind, covered in dark fur, and feed on their mother’s milk inside a den; their eyes open between 1 week and 3 days and 2 weeks and 2 days of age. The species begins to walk between 2 weeks and 4 days and 4 weeks. A typical lifespan for the bush dog is from 5 to 15 years, with a maximum recorded lifespan of 14 years and 1 month, and a theoretical lifespan ranging from 7 to 14 years and 1 month. The female reaches sexual maturity between 7 months and 3 weeks and 1 year. The adult stage, characterized by hunting behavior and the ability to reproduce, lasts from 10 months to 13 years and 8 months.
