How old is a male dog when he becomes fertile? Get Your Pet Thinking

At what age can a male dog breed?

Now that we know at what age male dogs are fertile, we must understand that for them this is strictly reproductive. This means that male dogs are only interested in copulating when they detect the presence of a female dog in heat. For the same reason, a female dog will only allow mounting when she is in heat. Only when they are fertile can fertilization occur.

If your dog is in heat, they wont always want to mate with a male. Read our article on why my female dog won’t accept a male for more information.

Reasons why a male dog cannot breed

Some dogs may suffer from diseases that cause sterility or anatomical malformations that prevent mounting and/or successful copulation. To know for sure whether or not a male dog is fertile, you can consult your veterinarian about a fertility test.

Additionally, hormonal abnormalities, underdeveloped or retained testicles, genital tract infections such as brucellosis, hypothyroidism or fever can all cause infertility in male dogs. Some dog tumors can also cause impotence. It is important to remember that dog breeding should not be carried illegally in homes and/or establishments.

What Can You Do To Ensure Mating Is Successful?

Surprisingly, male dogs appear to be more stress sensitive than females during mating. Successful matings are more common when the male dog is in its own environment. For this reason, females are usually taken to the male dogs home for breeding.

The time of mating is extremely critical and it is highly recommended that you have tested your female to determine the optimal days for breeding. For most females, the best time for breeding is between the tenth and fourteenth day of oestrus. However, some females ovulate as early as the third or fourth day or as late as the eighteenth day. Blood tests will assist in determining the best period for your dog.

It is normal to arrange for two matings for your dog, often twenty-four or forty-eight hours apart. Check these details with the owner of the stud when making initial enquiries. Also, inquire as to the procedure if your female dog does not become pregnant as a result of the stud service. It is common for owners of the male dog to offer a free service next time.
