A new study from UC San Diego suggests dogs may have a more basic form of jealousy that evolved to protect social bonds from interlopers. Dogs exhibited aggressive behaviors like snapping and pushing when owner showed affection to a stuffed dog, indicating they were motivated to break up the connection.
Researchers tested dogs' reactions to owners' affection for realistic and non-realistic objects, finding stronger jealous behaviors towards the dog-like object. This study suggests jealousy may have a primordial form in animals, including humans.
A recent study suggests that dog bites pose an unknown public health risk, while ignoring the health benefits of dog ownership. Research is needed to improve care and estimate dog bite incidence to develop effective risk management strategies.
