Castration/ Neuter

This is a simple procedure to remove your pet's testicles through a small incision. It does not change your pet's personality other than calming the need to "mark” his territory and reduce potential for aggressive behavior. We recommend neutering your pet around six months of age before he develops any negative behaviors. There is conflicting data about waiting to neuter your dog.  Please discuss with your veterinarian if you have any questions.

After a pre-surgical exam and vaccinations are given you may schedule your pet's procedure. You will need to fast your dog from 10 PM the night before the procedure, then he will be brought into the clinic between 8 & 9 AM on the day of the procedure. Your pet will be put under anesthesia for the procedure, which takes about 1/2 an hour. Your pet will be ready to go home that afternoon with some simple post op care. For the first week you will need to examine the area for redness, swelling, or drainage. Swelling is more common in older dogs.  Dogs should be taken on short walks with a leash. Play should be limited and no baths for both cats and dogs is recommended.

Benefits to neutering your pet include:

  • Eliminating annoying sexual habits such as marking territory both out of doors and inside.
  • Reduces the urge to mount other animals and other objects.
  • Allows dog to feel at ease in his own surroundings vs. roaming to find females. (In addition reducing your pet's chance of getting struck by a car, being in a fight or running away.)
  • Male animals left intact may become aggressive towards other animals and people.
  • Lowers your pet's chance of developing testicular cancer and prostate infections.

Neutering your pet will not make him fat and lazy but it will lower his metabolism by 25%. Therefore, you will need to reduce his calorie intake and keep an eye on his weight to prevent unnecessary weight gain. Genetics, amount of calories fed and how much exercise your pet gets will determine that. As your dog naturally matures, he may start to reduce his activity level, which may cause for it to appear that the neuter is to blame.

Wouldn't you rather be a pet that has a chance to live a longer, healthier life and with a calmer disposition? I know I enjoy it.
