Best Age To Breed A Dog (Male & Female)

The appropriate age to breed a sire(male) or a dam(female) depends on several factors such as the breed of the dog, size, the female’s heat cycle, health of the dogs, sexual maturity, etc.

It is irresponsible to breed a female dog too early or on her first heat as that may cause potential health risks for puppies and the dam. Attempting to breed dogs before they reach their full size and maturity will result in grave danger to the dam as her body is not yet equipped to handle the pregnancy stress.

Breeding the dogs too old will result in low sperm quality for the male dog and possible health complications in the female dog, along with fewer puppies in the litter being born.
