Pet Topic: Neutering is key to controlling Rarotonga’s dog population

Neutering is a key measure for managing dog populations, particularly in resource-limited island environments like ours where uncontrolled breeding can lead to serious problems, writes Dr Rose Hasegawa, medical director of Te Are Manu Veterinary Clinic.

Not only does sterilization help control the dog population, but it also provides significant health benefits to the animal.

One of the most pressing issues facing many communities is dog overpopulation. A female dog, if not spayed, can produce an astonishing number of puppies in her lifetime. The average dog can produce two litters per year, with four to six puppies per litter, though it is not uncommon to produce more. Over a 10-year period, a single dog can produce up to 120 puppies. When you consider that her offspring can also reproduce, the population can quickly get out of control.

This exponential growth has led to an increase in the number of stray or unwanted dogs, resulting in challenges in managing these dog populations. Stray dogs can be malnourished, sick and injured, and can become a public health concern. Outreach programs like our Pune Spay/Neuter Clinic play a vital role in curbing this population surge, preventing countless animals from suffering and reducing the burden on local resources such as the SPCA.

In addition to controlling the dog population, neutering provides many health benefits to dogs. Neutering female dogs significantly reduces the risk of ovarian and uterine cancers and virtually eliminates the risk of potentially life-threatening uterine infections such as pyometra. Additionally, neutering before the first estrus greatly reduces the risk of mammary tumors, which are often malignant.

For male dogs, neutering can reduce the likelihood of testicular cancer and prostate disease. Neutering can also reduce undesirable behaviors associated with testosterone, such as aggression, prowling for a mate, and marking territory with urine. These behaviors can lead to injuries from fights or accidents that are common in intact dogs.

In addition, neutering can help dogs live longer and healthier lives. Studies have shown that neutered dogs tend to live longer than intact dogs, possibly because neutering reduces the risk of certain diseases and behaviors that lead to injury or death.

As you can see, our Puna Spay & Neuter Clinic is back in operation. Thanks to the Cook Islands Tourism Board, we can once again provide free dog sterilisation services to the Rarotonga community. We had great success in the Tupapa community last month and this Tuesday we are running a clinic in Matavera. Our monthly clinics will continue to operate so we encourage the community to take advantage of the convenience of a sterilisation clinic close to home whenever possible.
