Why should you spay/neuter your pet?
Your pet's health and longevity
The average lifespan of spayed and neutered cats and dogs is demonstrably longer than the lifespan of those not. A University of Georgia study, based on the medical records of more than 70,000 animal patients, found that the life expectancy of neutered male dogs was 13.8% longer and that of spayed female dogs was 26.3% longer. The average age of death of intact dogs was 7.9 years versus a significantly older 9.4 years for altered dogs.
Another study, conducted by Banfield Pet Hospitals on a database of 2.2 million dogs and 460,000 cats reflected similar findings, concluding that neutered male dogs lived 18% longer and spayed female dogs lived 23% longer. Spayed female cats in the study lived 39% longer and neutered male cats lived 62% longer.
The reduced lifespan of unaltered pets can, in part, be attributed to an increased urge to roam. Such roaming can expose them to fights with other animals, resulting in injuries and infections, trauma from vehicle strikes and other accidental mishaps.
A contributor to the increased longevity of altered pets is their reduced risk of certain types of cancers. Intact female cats and dogs have a greater chance of developing pyometra (a potentially fatal uterine infection) and uterine, mammary gland and other cancers of the reproductive system. Neutering male pets eliminates their risk of testicular cancer and eliminates the possibility of developing benign prostatic hyperplasia which can affect the ability to defecate.
Curb unwanted behaviors
Intact dogs are more prone to urine-marking than neutered dogs. Although urine-marking is usually associated with male dogs, females may do it too. Spaying or neutering your dog should reduce urine-marking and may even stop it altogether.
For cats, the urge to spray is extremely strong in those not altered, so the simplest solution is to alter by 5 months old before the problem arises. Neutering solves 90% of all marking issues, even in cats who have been doing it for a while. It can also minimize howling, the urge to roam and fighting with other males.
In both cats and dogs, the longer you wait, the greater the risk of the surgery not doing the trick because the animal has practiced the behavior for a longer period of time, thereby reinforcing the habit.
Other behavioral problems that may be alleviated by spay/neuter include:
- Certain types of aggressive behavior.
- Roaming, especially when females are in heat.
- Excessive barking and mounting activity.
- In-heat behaviors such as yowling/vocalizing, rolling and demanding behaviors.
It is important to understand that, while spay/neuter may be helpful in resolving certain behavior problems, it is not a cure-all, and some behavioral challenges may require multiple solutions. Also, while having your pets spayed or neutered may help curb certain undesirable behaviors, it will not change their fundamental personalities.
