This is great news for dogs and dog lovers: there is a new method to sterilize male dogs without surgery! It's called Esterilsol, a solution of zinc gluconate, L-Arginine and water that is shot into the dog's scrotum.
The method—also called zeutering—will sterilize your dog within a month. It has now been approved for 10-month and younger dogs in the United States. So far, about 300 dogs have been neutered in this way.
The new system will greatly help shelters all through the nation, reducing costs and speeding up the neutering process.
And I don't know about you, but if I'm going to be sterilized, I would rather have a shot in my scrotum than having my balls cut and thrown into the trash. [The Dogs]
