Fertility After Bleeding
The fertile period often begins about nine or ten days into a female dog’s heat cycle and lasts about five days.
Female Dog’s Heat Cycle
Female dogs normally bleed for around half of their heat cycle, which is usually 7 to 10 days. After about 9-10 days, the bleeding often becomes more watery or stops. This is when female dogs are often most fertile.
Pregnancy and Mating
- Mating dogs remain "tied" or "locked" for about 15 minutes. They cannot be safely separated during this time without risking injury.
- The pregnancy of a dog generally lasts about 63 days from fertilization.
Male Dog’s Fertility
The reproductive lifespan of a male dog often starts around six months of age. Male dogs typically remain fertile throughout their lives. However, sperm quality and quantity may decrease with age, affecting fertility.
