Article: The "Quick Fix?": Neutering as a Treatment for Aggression (No replies)
The truth is, there is very little evidence to support the idea that spaying or neutering is an effective strategy for reducing aggression in dogs. Most controlled scientific studies on this question (and there have been many!) show that whether a dog is spayed or neutered has no impact at all on the likelihood that they will be aggressive in any given circumstance.... Interestingly, under one type of statistical analysis, the researchers actually found a modest increase in the risk of aggression (towards strangers, specifically – no change in the other categories) in male dogs neutered between the ages of 7-12 months. The authors discuss some possible reasons for this finding and acknowledge that we don’t have enough information yet to know if this is a real effect vs. a statistical fluke of some kind, but it’s not the first study to show similar results.
