The effects of neutering your dog are not permanent. Sterilization injections through chemical surgery or taking hormonal drugs can prevent dogs from going into heat. However, long-term use of hormonal drugs will cause great damage to the dog's body and can also lead to endocrine disorders. Or it can be performed through surgical operation. After the operation, the purpose of permanently preventing the dog from going into heat can be achieved.

Methods to prevent and treat pregnancy in dogs

1. Get a contraceptive injection. This is a hormonal preparation. During the period of injection, the pet will not be in estrus, but once the injection is stopped, it will return to estrus after a few months. However, this method has been gradually phased out due to the risk of side effects.

2. Take birth control pills. Give the female dog birth control pills before she goes into estrus to suppress hormones and avoid pregnancy. However, like contraceptive injections, these are short-lived and need to be given continuously, and they also have side effects for dogs. It is not as good as surgical sterilization, which can be done once and for all.

3. Get sterilized. Sterilization surgery mainly removes the dog's uterus and ovaries to make it lose its ability to reproduce. It is the most thorough and fundamental method of contraception.

4. Wear dog safety pants on the dog so that other male dogs cannot mate.
