It looks like dogs may realize when their owner tells them "I love you."
Canine Cottages' new study followed four dogs for a week while tracking their heart rates. When the owners told their dogs they loved them, the dog's heart rates increased on average 46-percent. The study also found dogs' heart rate decreases by 23-percent on average when they cuddled with their owners.
If you want to know how dogs say “I love you back, veterinarian Dr. Heather Venkat says it happens with these actions:
A dog curling up next to its owner
Wagging their tail when being greeted
Bringing a toy to the owner, which signals trust
Showing their pet parent their tummy
While in pain, they go to their owner
