A lot of dog-loving people may have had problems with dogs. It is easy to have a dog, but dogs usually give birth to five to six children a year, and every dog can have even five to six children, and the amount of money cannot sustain a geometrical increase, with the result that there are countless stray dogs in the streets who are less likely to die.

The first thing that happens to many dog-loving people abroad is to have their dog sterilized, which is a rational manifestation of how the dog's invention can save the dog from the pain of the operation and save the owner's money. But for animals, it's kind of cruel, because animals have the right to have children in love.
So, is there any contraceptive method that can be effective without animal sterilization?
There's a dog master who has come up with such a crazy way:
Cover a significant part of the dog with a piece of iron and put it on the dog's tail, with a fixed effect. The size of the iron tablet is so wide that even when dogs lift their tails, they protect the virgin land from aggression. Even if the dog runs, the iron blade will not shake, and it will not hurt the dog by friction. So dogs can go out and play freely, without fear of being used by other dogs.

And so cleverly invented, there's also the name of the oceanic air: forcing locks.
However, there are shortcomings. After all, it's an iron thing, and the puppy himself might feel a little weird, always looking back and seeing what he's wearing. But whoever finds himself wearing an iron underpants would be unhappy, huh?
