Does spaying and neutering reduce aggression?
Does spaying and neutering reduce aggression in canines where a claim can be made that it will protect the public? A significant number of canines that have been sterilized are responsible for killing people and data shows high numbers of sterilized canines show up on dog bite incident reports.
ACF(American Canine Foundation) is preparing response briefs in our federal lawsuit, Defense attorneys in their briefs are making claims that spay and neuter will protect the public by stopping canine aggression. ACF is moving forward in our federal lawsuit against LA County, San Francisco and California State Agencies.
Below is a text taken from data using scientific proof from an FDA Federal Study addressing testosterone in canines:
DR POLLEY DVM Addressing The Testosterone Issue
"Testosterone plays a role in modulating certain behaviors such as roaming, urine marking in-doors, sexual mounting and aggression toward other dogs (versus playful activity or dominance). Neutersol reduces the male hormone, testosterone, by 41-52% while surgical castration reduces testosterone by 95%. These behaviors may persist after either neutering method.
While testosterone plays a role in affecting certain sexually dimorphic behaviors, it is not the only factor. In fact, the veterinary behavioral textbooks point out that there are multiple contributing factors with regard to these behaviors. Surgical castration does not completely eliminate these behaviors. The controlled scientific studies that have assessed the effects of surgical castration with regard to behavior have shown that most dogs continue exhibiting these behaviors. Aggression toward humans shows little significant effect after surgical castration. Surgery can have an effect in some of these, but is far from absolute. The FDA has reviewed the data for both surgery and Neutersol and included wording in the prescribing information of Neutersol addressing this fact, "As with surgical castration, secondary male characteristics (roaming, marking, aggression and mounting) may persist."
Here are some research publications that conclude that early spay/neuter
correlates with a high incidence of ACL damage and cancer.
Texas Tech University has PhD's that have published a study on ACL and
spay/neuter correlation. This type of injury is one of the most painful to
