how soon can a puppy be bred
Breeding Dogs: The Tie. Male dogs can start to have sperm at seven months old, but ten months is more common. Young dogs do not have quality sperm. Almost all dogs will have sperm by one year. Stud dogs are at their prime between 18 months and 4 years old (or 5), after that, the quality of the sperm starts to lessen, and the ability to penetrate eggs, lessens. By 10 years old, most stud dogs do not produce sperm that will impregnate a bitch. A tie is a natural phenomenon of dog breeding in which the bulbus glandis of the male's penis swells inside the bitch's vagina.
