But licks aren't the only way you can tell your dog's head-over-heels for you. "Dogs show affection to humans in lots of ways," Ebbecke said. If your dog leans into you or rests his head or paw on you, it's a really good sign.
And there's one thing that people don't often realize is a real sign of love, Ebbecke said. "Sometimes when dogs offer a soft stretch towards a person, especially if they haven't been resting or lying down recently, it's actually very close to an 'I love you' gesture," Ebbeck said.
