How is a dog castrated?

Answer 1

Your question is how were animals neutered, so I assume that you wish to know how they were neutered in the past VS present times?

In the days of the wild west animals were cast and their legs tied, while one or two hands held the animal down and another did the neutering. This was done by grasping the animals scrotum and making a cut or incision into it over first one testicle, then the testicle was drawn outside the animals body and either pulled until the cord broke or scraped until it was severed from the body. The cord could not be cut directly as the clean incision would cause the animal to bleed to death. Once one testicle was removed then the procedure was repeated for the other testicle. There is held the belief that some cowboys on the range would actually bite the cord to separate it, but I do not know if this is true, but it seems a valid theory for the time.

Later 2 devices were created to do this same process these were (and are still) called Emasculators.

1. The Rubber band Emasculator was a device which held a thick rubber band, once the 2 handles were depressed it would stretch the rubber band so that it could be placed over the animals scrotum and pushed upwards to the body, Then you would release the handles and the rubber band would then close over the thin portion of the scrotal sac thus cutting off the circulation to that area where it would die off and fall off naturally. This process may still be used in some parts of the country or in other country's.

2. Compression Emasculators are a pincer like device that would be placed over the spermatic cord (thin area of scrotum) and compresses the cords by squeezing the handles, until the cord is severed within the body. This method allows the bull, now considered a Bullock to retain the male hormones while preventing fertility. The resulting animal is heaver in the neck and chest like a bull and does not gain the height of a steer. This procedure is more humane but the animal maintains the hormones of a bull, it too is still used today.

One final method of creating a bullock was to use the cut into the testicular sac where it is thinner to expose the spermatic cord and scrape the cord with a knife till it separates, and repeat on the other side.

Present Veterinary Sterilization is a much kinder process and is done under general anesthesia, The procedure (once the animal is anesthetized) is quite similar to the first example, in that the scrotal sac is either removed or entered and each testicle is removed, the spermatic cord is either clamped till it severs or it is scraped till it severs, then the testicle is removed from the body. The resultant incision is then doused with an antiseptic solution like betadine and sutured closed.

Answer 2

put a rubberband around them until they fall off
