Oh, be still our hearts, if this is the most endearing new study reveal we've ever heard!
Canine Cottage conducted a study in which they had four different pups fitting with a special heart rate tracking collars. These collars indicate what gets the pups excited when interacting with their owners. Over the course of seven days, the average heart rate for the four dogs was 67 beats per minute.
When the dogs heard their owners tell them. "I love you," their average heart rate skyrocketed to 98 beats per minute!
