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.
I know I must not laugh about this image, but I am. There's something comical about all these cats waiting for surgery. Of course, I wouldn't be laughing if I were the one about to get my balls sliced and diced.
