There have been two types of contraceptive pills on the market. One is for male dogs and has a powerful sperm-killing effect. It is said that the effect is pretty good. However, the greater the effect, the greater the consequences are. The incidence of testicular cancer in dogs who have taken contraceptive pills has greatly increased.
The other type is for contraception for bitches. The drug contains megestrol acetate, which is more effective in delaying estrus and has no effect on contraception.
and after taking contraceptive pills, a series of side effects will appear, such as vomiting, convulsions, etc. Some dogs will even lose their fertility from then on, which is not worth the loss.
Especially some owners who don’t know the truth even take human birth control pills to their own dogs, and the dosage is not considered. In the end, it not only leads to infertility, but also causes serious liver damage and poisoning and needs to be sent to the hospital for emergency treatment.
