PetMeds® Does Neutering Reduce Aggressive Behavior in Pets?

One of the biggest reasons pet owners neuter or spay their pet is to supposedly “calm them down” and/or improved unwanted or aggressive behaviors.  However, research in recent years actually has been conflicting on this with several studies showing that aggression is actually higher in the neutered male dogs. ertain cancers (like prostate cancer) and diseases are actually higher in the neutered male.

When looking at populations of dominance aggressive pets at veterinary university behavioral clinics, most of the presenting pets are indeed already neutered.  In addition, it is also interesting to note that certain cancers (like prostate cancer) and diseases are actually higher in the neutered male.

In spite of this it is still recommended to neuter male pets to help control pet populations, however, I usually recommend waiting until a male pet is sexually mature at 1 year of age to neuter them.

    Thanks for sharing. Most neutered pets are fine. It is just that we are finding that there are certain increased health risks in neutered male animals that was not appreciated or understood years ago.

  3. I had a healthy happy Beagle who lived to 16 plus years he was intact his whole life. The only medical problem he encountered due to being unmutilated was that he was misdiagnoses at one of Boston’s larges Animal Hospital. When I brought him in for constipation problems; all the Vet saw was his testicals and immediately formulated a diagnosis that would put them at the center of the problem. Two months later I brought my dog in almost dead and it was discovered he had been internally bleeding for months, and trying to pass his own digested blood is what was causing the problems with defecation.
