When a female dog is on heat or when she is on her estrus stage, then she can get pregnant when mated with other dog. The female dog can get pregnant on her first estrus stage; there are breeds of dogs that are already sexually mature as early as six months of age. It is not advisable that a female dog gets impregnated on her first estrus stage because there is a big chance of miscarriage. Young female dogs on their first estrus cycle are not yet fully developed and their bodies are not yet ready to carry and nurse puppies.
When a female dog is on heat, she releases a chemical called pheromone. This chemical can be smelled by male dogs in the neighborhood and they would try to mate with the female dog. When a male dog has successfully ejaculated sperm on the female dog, then the female dog can be pregnant. A female dog not on heat, on the other hand, would not allow male dogs to mate her.
A female dog can be pregnant on her first estrus stage and she can continue to get pregnant even after several years or during her senior years. Dogs do not undergo a menopausal stage unlike human females, but their fertility is affected as they grow older. So the best solution to prevent her from getting pregnant is to spay her.
