Here’s an article from two veterinarians in Vail Colorado that explain the benefits of spaying and neutering your pet…..
There are many theories when it comes to the medical and behavioral effects of spaying and neutering dogs and cats. It is a controversial subject and there are numerous viewpoints out there among trainers, breeders, and within the veterinary profession.
The chief intent of this article is to state proven scientific facts. we’ll go through the medical benefits of neutering and spaying both dogs and cats, and finish with our personal beliefs on the behavioral changes that can occur.
The principal benefit of spaying female dogs and cats is the prevention of mammary cancer. A dog spayed before her first heat will have a near zero chance of developing mammary cancer later in life. After the first heat, this incidence climbs to 7 percent, and after the second heat the risk approaches 25 percent. Statistics are similar in cats.
The prevention of what is frequently a very difficult and potentially fatal form of cancer is reason enough to spay our dogs. Another potential condition in intact females is a bacterial infection of the uterus called pyometra. Treatment is surgery in a potentially unstable patient and can be very costly.
Less common conditions such as uterine and ovarian cancer are 100 percent prevented by spaying. Intact female dogs come into heat about every 8 months, resulting in bloody vaginal discharge and an unpleasant odor.
The major health benefits involved in neutering a dog involve the prostate gland. As dogs age, the prostate will gradually enlarge. This is known as benign prostate hyperplasia or BPH (think Flomax commercials). The prostate under the influence of testosterone is also predisposed to infection. This is an extremely painful and sometime life-threatening condition which is not likely to resolve without neutering and often invasive surgery.
Other medical conditions that are prevented include testicular cancer, along with certain types of hernias and perianal tumors. The effects of neutering male cats are more behavioral and are listed below.
There are no concrete facts when it comes to the behavioral changes seen in spayed and neutered dogs and cats. Neutering male dogs and cats can reduce urine marking in your house, aggression towards other dogs, and territorial aggression. It is important to realize that these behaviors can become a habit and continue after neutering.
Many experts say that once a pet is older than 1 year of age and still intact, undesirable behaviors are more likely to become permanent even if they are neutered at that time. The most dangerous behavior seen in intact males is roaming, i.e., running away to look for a mate, because it leads to animals running away as well as car accidents.
The reproductive tracts of the female dog and cat are dormant for most of the year. From a behavioral standpoint, the animals will â€śact spayedâ€ť most of the time and no personality changes should be noted with spaying. When in heat, females are more likely to be aggressive and can show erratic behavior such as howling and writhing on the ground. And an intact male can detect females in heat from miles away so it is not safe to leave them outside unsupervised.
The medical benefits resulting from spaying and neutering pets lead to longer and healthier lives. In addition, the majority of animals will be more relaxed and less prone to undesirable behavior.
Most Veterinarians recommend spaying and neutering dogs and cats when they’re about six months of age.Â Please consult with your local Veterinarian to discuss their recommendation for their pet.Â
