It is recommended that female dogs be neutered after their first estrus

Generally speaking, it is best for female dogs to be neutered after their first estrus. Because the female dog has gone through an estrus, the pituitary gland, ovaries and the entire hormonal cycle have gone through it. At this time, the female dog's sexual orientation is stable, and all aspects of personality and development have reached the most complete stage. It is the best time for sterilization surgery.

It is best to neuter male dogs after 8 months

As for male dogs, it can be determined according to the owner’s wishes. Generally, male dogs will have the concept of occupying territory after they reach sexual maturity. Many owners do not like their dogs raising their legs to urinate everywhere at home, so they choose to have male dogs neutered when they are 6 months old. But because it has not gone through the stage of sexual maturity, it may not be good for physical development. Therefore, most animal doctors recommend that male dogs be sterilized at 9 to 10 months. Although they can already lift their legs by this time, their male hormones have begun to develop, which is better for the dog's health.

Generally speaking, as for the age for sterilization, doctors say that in theory it can be done at any age. However, considering that the operation requires general anesthesia, there are certain risks. It should only be done as a last resort for older dogs. Young dogs are recommended to be sterilized from 4 to 6 months abroad. However, some doctors consider the growth and development needs of male dogs. Surgery can be performed again after 8 months.
