When is the best time to breed Tibetan Mastiffs? It is best to breed Tibetan Mastiffs about 18 months after the birth of female dogs and about 24 months after the birth of male dogs. After Tibetan Mastiffs reach adulthood, they will go into estrus twice a year, in spring and autumn. At this time, Tibetan Mastiff females Dogs will bleed, and the best time to breed is when there is no blood at all or only slight bleeding.

The Tibetan Mastiff will go into heat for the first time 8-12 months after birth. At this time, the reproductive organs have matured, but it is best not to breed the Tibetan Mastiff at this time. Because at this time, the various organs of the dog’s body have not grown enough to bear the pressure of pregnancy. Therefore, it is best to breed Tibetan Mastiffs when female dogs are around 18 months old, and when male dogs are around 24 months old. If Tibetan Mastiff dogs are forcibly bred before this time, it may easily lead to dystocia and other conditions.

When Tibetan Mastiffs reach adulthood, they will go into estrus twice a year, in spring and autumn, that is, from March to May and from September to November. Tibetan Mastiff female dogs will bleed during estrus, which is what we commonly call "menstruation". It is not suitable to breed when there is a lot of bleeding. The best time to breed is when there is no blood at all or only a little blood.

During estrus, you should choose a soft kennel for your Tibetan Mastiff. It is best to have two kennels that can be replaced with each other for easy cleaning. We must pay attention to the cleanliness of the kennel. After washing, it is best to expose it to the sun for sterilization and disinfection. Try not to bathe your dog during estrus, as the dog’s reproductive organs are susceptible to infection at this time. If parents have no plans to breed Tibetan Mastiffs with puppies, it is best to put the Tibetan Mastiff in menstrual pants, which can avoid pregnancy to a certain extent and is also cleaner and hygienic for the dog itself.
