It's not advisable to breed a 10-month-old Boston Terrier. While they might be sexually mature at this age, their physical development is not yet complete. Breeding them too early can negatively impact their health and the health and quality of their offspring.
A 10-month-old Boston Terrier is not ready for breeding. At their first heat cycle, they are only sexually mature, not physically mature. Their bodies haven't finished developing. Breeding at this stage is unsuitable. Generally, Boston Terriers should only be bred after 12 months, around their second heat cycle. By this time, their skeletal structure is more developed, which helps prevent complications such as difficult births caused by a narrow pelvis.
Furthermore, even when a dog reaches maturity, it's best not to breed them immediately at the start of their heat cycle. It is recommended to wait about a week, as the female dog will be in her ovulation period and have a higher chance of conception. To ensure successful breeding, it is usually best to breed them twice with a two-day interval between each breeding. If the dog experiences symptoms like decreased appetite, lethargy, and gradually enlarging mammary glands after breeding, it indicates a successful pregnancy. It's important to provide them with adequate nutrition to support fetal development during pregnancy.
