Chihuahua is two years old. It's a male. I am very excited these days. What should I do? Do you want to sterilize it or not?
Estrus is a bitch's patent, but not a male dog. You mean male dogs are always hooligans?
If there is no bitch in estrus, the male dog is always mating, which is a bad habit. Don't spoil it and resolutely correct it. If you have no patience, you will have to be sterilized.
