When Should You Have Your Australian Shepherd Spayed or Neutered?

It is common in the U.S. to have your male Aussie neutered at 6 months old and your female spayed 3 months after her first heat cycle. There are exceptions to these circumstances, such as shelter pets that may have been sterilized younger. Some pet parents prefer to wait until their Aussies reach skeletal maturity before sterilization, which could be between 12 and 15 months of age. Your veterinary surgery may have specific policies in place, but they should be willing to discuss your and your individual dog’s needs.

Why Is It Important to Spay or Neuter Your Australian Shepherd?

Whether to spay or neuter their dog is an important decision that every owner must make as their pet approaches adulthood.

1. Affects Health and Lifespan

Studies have shown that dogs that are spayed or neutered have longer lifespans than those that have not been. The life expectancy of a male that has been fixed is 13.8% longer, and females that have been spayed live 26.5% longer, so if you want to keep your Aussie around for a long time, this is the best option for both of you.

Aussies that have been spayed or neutered are also said to be healthier and have reduced risk of certain cancers, such as ovarian, uterine, mammary, and testicular cancers.

2. Curbs Unwanted Behavior

If you’ve ever been around a dog in heat, you already know what we’re talking about. From urine-marking to having puppies, certain behaviors can be curbed by having your Aussie spayed. Here are a few more behaviors that can be reduced with the procedure if they are hormonally driven.

  • Aggressive behavior (certain types)
  • Excessive barking
  • Mounting
  • Roaming (females in heat)
  • Howling/vocalizing/rolling
  • Other demanding behaviors

If you are looking to have your Aussie sterilized due to behavioral concerns, it is best to consult with your veterinarian and a registered behaviorist first, as some problems can be worsened by sterilization.

3. Saves Money

While having your Aussie spayed or neutered to save money isn’t usually the main reason to have it done, it does stand to reason that not having the procedure will affect your budget in the long run. Caring for a pet with reproductive cancer or pyometra can cost thousands of dollars, while spaying or neutering is inexpensive.

On top of that, think of having six or seven new puppies to feed, and you’ll see the savings and an excellent reason to have your Aussie spayed or neutered when they are old enough.


Final Thoughts

While it’s each pet owner’s decision whether to have their Aussie spayed or neutered, statistics point toward it being the best idea. Not only is it better for the health of your Aussie, but it also cuts down on the stray population, which is steadily growing.
