Spaying and neutering is the best way humans can fight animal overpopulation. Unaltered animals will always be vulnerable to urges to procreate, and human error means that we can never guarantee that our dogs are under our control 100% of the time.
Why even one unspayed animal is disastrous: ONE average unspayed female dog and her offspring can produce 67,000 dogs in 6 years. In comparison, one female human who has back-to-back pairs of twins for 6 years (the chance of this happening 9 times to the same woman is less than 1/1,000,000,000,000,000!) would produce AT MOST 18 children. Comparing these two numbers goes a long way in explaining why America has a pet overpopulation crisis – the human birthrate simply cannot compete with the canine birthrate!
Spaying and neutering also benefits you and your dog! Getting your dog fixed will:
-Eliminate the risk of certain types of cancers and fatal infections
-Reduce your dog’s urge to roam, fight with other dogs
-Reduce or eliminate urine marking
-Reduce assertive/aggressive behavior in most dogs
-Reduce barking and mounting behaviors
