When a dog licks your face, jumps into your lap, or barks like a banshee when you come through the front door, it simply means they’re crazy about you.

But did you know that your dog’s heartbeat actually soars when you tell them, “I love you?”

Well, according to a recent study conducted by the folks at Canine Cottages, that well may be the case.

After equipping a quartet of test pups with heart rate monitors, the dogs were guided through a series of scenarios over the course of seven days to see how they’d react to a variety of stimuli.

The tracking data revealed the four dogs averaged a resting heart rate of 67 beats per Minute.
