Deciding to breed your dog is a big decision and a choice that is taken after giving it a thought. However, before deciding, you need to know when can a male dog breed.

What Is The Actual Age Of A Male Fog To Start Breeding?

A male dog’s sexual maturity can develop at a different age depending on the breed.

However, most males can reproduce effectively by six months and reach complete sexual development between 12 and 15 months.

The American Kennel Club guidelines and rules prohibit the registration of a litter whose sire (a term for healthy unneutered males) was either younger than seven months or older than 12 years at the time of mating unless additional paperwork is presented. 

Male dogs are thought to be capable of having a litter at any time after reaching sexual maturity, even if they are still intact. 

They are the most fertile at 12 to 15-month age and have the highest testosterone levels.

During this time, your dog might engage in activities like marking his territory with urine and roaming. These are standard traits of any unneutered male dog, but they are more prevalent at this age.
