Adoring pooches routinely produce tears of happiness during reunions with the humans they adore most, a world-first study has shown.
Dogs get teary for their favourite humans
Dogs produce happy tears in response to their favourite humans, adding a new dimension to an age-old story of love and companionship.
A Japanese study is the first to show positive emotions can stimulate tears in animals other than humans, namely man’s best friend.
Researchers carefully measured the tear volumes of 18 dogs under three scenarios.
The first set the baseline for the study – normal tear volumes when the dogs were chilling at home with their owners.
