Researchers: Hormone responsible for aggressive dogs

UA researchers: Hormone sparks dog aggression
Posted
and last updated

If you know your dog gets aggressive around other animals, you may hesitate bringing them out in public, but a new study done by the University of Arizona Canine Cognition Center found a link between hormones and dog aggression.

Researchers say a hormone called vasopressin spiked when dogs got angry and lunged or growled at another animal. This hormone is also linked to aggression in humans.

Researchers say identifying this hormone link could help lead to chemical therapies down the line.

Researchers say a common misconception about solving aggression in dogs is to get your pet neutered, but there's no science saying that works.
