Understanding the Alaskan Malamute's Reproductive Cycle

Female Alaskan Malamutes do not have the typical twice-yearly estrus cycle seen in many domestic dogs. Their cycle resembles that of wolves: usually one estrus per year, triggered by lengthening daylight in late winter (often February). The estrus period lasts about 2–3 weeks, with a fertile window of 3–5 days around days 10–14. Signs include vulvar swelling, discharge, and increased male interest, but the female may be selective about mates. Owners should consult experienced breeders or veterinarians for guidance on breeding timing and health.
