What You Should Know About Neutering

You may be a first-time dog owner with little to no knowledge of neutering. All you know is that your vet is recommending it, or you know a few owners who have neutered their dogs. The following is information that will come in handy during the neutering process.


Neutering is a surgical procedure involving the removal of testicles leading to sterilization. Although it may seem like a common procedure the owner makes regarding their dog, it is important to make the decision with your vet.

Your JRT will be examined to know whether its testicles have descended or not, as they require different procedures. If they have descended, the incision is made in front of the scrotum, below its penis. If they haven’t, the vet locates them and makes the incision.

The vet will also draw your Jack’s blood and test it to see if he can be anesthetized. If he is cleared for surgery, the vet will instruct you not to give him any food from approximately eight hours before the procedure.


After the surgery, you will need to take care of your dog so it can recover properly. Some of the things you have to put into practice include:

  • Restricting its activities for the next 10 days after surgery, however, ensures it gets some exercise, such as walking.
  • Monitor the surgical site for any signs of swelling, discharge, or redness. Call your vet as soon as possible if you notice any of them.
  • Ensuring your Jack does not lick its incision by using an E-collar.
  • Administering the pain medication prescribed by the vet.
  • Monitor its bathroom habits, especially if it does not pee in the next 24 hours after surgery. If this is the case, inform your vet as it may be a sign of surgical complications.
  • Look out for signs of surgical complications. Your vet will provide a detailed list that includes vomiting, breathing problems, discharge, and pale gums.


Some dog owners feel neutering goes against nature and that Jacks should be left to breed whenever they want. However, before you take such a stance, it is vital you understand the benefits that come with neutering. They include:

  • Health: Neutering drastically reduces the chances of your Jack getting testicular cancer. It also decreases the chances of developing hernias.
  • Overpopulation: One of the major contributors to attacks and bites by stray dogs is the irresponsible breeding that comes with overpopulation. A neutered dog cannot mate, therefore leaving breeding to those planned for.
  • Reduced aggression: Testosterone is a hormone produced in the testes and responsible for psychological and physical changes in your dog. The hormone makes it exhibit territorial behavior and increases its sex drive and aggression. With the removal of the testes, your Jack will become calm and behave less aggressively.
