Cesar Millan
In the United States, seven puppies and kittens are born for  every one human. As a result, there are just not enough homes for the animals,  and four to five million dogs and cats are euthanized every year.
Sterilizing dogs and cats has been hailed as the most  effective method for pet population control. You can help save lives by spaying  and neutering your pet. If pets can’t breed, they don’t produce puppies that end  up in animal shelters to be adopted or euthanized. Currently, over 56% of dogs  and approximately 75% of cats entering shelters are put to sleep.
The perpetuation of myths about spaying and neutering and the  high cost cause many people to avoid the procedures, but the fact is  sterilization makes your dog a better behaved, healthier pet and will save you  money in the long run.
Many people, particularly men, have a hard time sterilizing  their pets, imposing upon their dogs their own feelings on losing reproductive  abilities. A dog will not feel like less of a “man” or “woman” after being  sterilized. It will not suffer an identity crisis or mourn the loss of its  reproductive capability. Your dog will simply have one less need to fulfill.
A dog’s basic personality is formed more by environment and  genetics than by sex hormones, so sterilization will not change your dog’s basic  personality, make your dog sluggish or affect its natural instinct to protect  the pack. But it will give you a better behaved pet.
Neutered dogs have less desire to roam, mark territory (like  your couch!) and exert dominance over the pack. Spayed dogs no longer experience  the hormonal changes during heat cycles that turn your pet into a nervous dog  that cries incessantly and attracts unwanted male dogs. Sterilized dogs are more  affectionate and less likely to bite, run away, become aggressive, or get into a  fight.
Another myth is that spaying and neutering cause weight gain.  Dogs do not get fat simply by being sterilized. Just like humans, dogs gain  weight if they eat too much and exercise too little or if they are genetically  programmed to be overweight. The weight gain that people may witness after  sterilization is most likely caused by continuing to feed a high energy diet to  a dog that is reducing its need for energy as it reaches adult size.
Dogs do not mourn their lost capability to reproduce. They  reproduce solely to ensure the survival of their species. They do not raise a  puppy for eighteen years. They do not dream of their puppy’s wedding. They do  not hope for the comfort of grandchildren in their old age. Female dogs nurse  for a few weeks, teach the puppies rules, boundaries, and limitations and send  them off to join the pack. Male dogs are not “fathers” in the human sense of the  word; they do not even recognize puppies as their own.
As for expense, today there are enough low cost and free spay  and neuter programs that this can no longer be an excuse! Even if these programs  are not available in your area, the emotional distress and money spent on  medical treatments you will save down the line makes it an investment that will  be worth every penny.
Sterilization reduces the risk of incidence of a number of  health problems that are difficult and expensive to treat. In females, it  eliminates the possibility of developing uterine or ovarian cancer and greatly  reduces the chance of breast cancer. Also, some females experience false  pregnancies and uterine infections that can be fatal. Prostate cancer risk is  greatly reduced in males. By sterilizing your pet, your dog will live a  healthier and longer life.
Efforts by programs such as SPAY/USA already seem to be having  an effect. In 1980, approximately 23.4 million animals were euthanized.  Twenty-two years later, the estimate was down to 4.6 million. In towns and  cities that have already implemented sterilization programs, the number of  companion animals who had to be euthanized is showing a decline of 30 to 60  percent.
The truth is that neutered and spayed dogs are better pets.  And though we’re heading in the right direction, the problem of euthanasia  continues. Be a part of the solution. Spay or neuter your pet today!
