    What's more heart-melting than Ryan Gosling shirtless on the big screen? How about Ryan Gosling next to his four-legged best friend, George? Or Jon Hamm on a walk with his dog, Cora? Or David Beckham squeezing Scarlett the French Bulldog in his arms? These talented men set aside plenty of time for the furry loves of their lives, i.e. their canine kids. This Father's Day, we're praising the hottest dog dads in Hollywood.  

    RYAN GOSLING 

    Canine Kid: George

    Why He's an Awesome Dog Dad: As if you needed another reason to find Ryan Gosling adorable, this hot actor loves his pooch George so much that they're seen everywhere together. From hikes to airports, George is Gosling's most loyal companion. Gosling even shares the limelight with him. He brought George along when he made an appearance on "Late Night with Jimmy Fallon."

    TIM TEBOW

    Canine Kid: Bronx

    Why He’s an Awesome Dog Dad: The New York Jets quarterback loves his Rhodesian Ridgeback as much as he loves football. But when Tebow left Denver to play for the Jets, he knew the dog, Bronco, needed a new name. He is now known as Bronx. We wonder if Tebow's dog knows how to kneel like his dad.

    Canine Kid: Cora

    Why He's an Awesome Dog Dad: The "Mad Men" star loves his German Shepherd mix Cora so much that earlier this year, he even guest starred alongside Hamm and his girlfriend Jennifer Westfeld in the PBS Kids animated series, "Martha Speaks." The dad-and-dog duo can often be spotted on walks around Hamm's Los Feliz home. We wonder if Cora's a Don Draper fan.

"I’m a really weird person that doesn’t like talking to other people, but I really like talking to the dog," Wentz once said.

Lutz told reporters, "Honestly, it was a long seven months that got longer and longer.  That’s a long time being away from my home, my friends and my dogs."

    ADRIAN GRENIER

    Canine Kid: All Dogs

    Why He’s an Awesome Dog Dad: Whether it’s babysitting his mom’s dog, Honey, or playing with "Entourage" Rottweiler Arnold, Adrian Grenier has built his own circle of canine compadres. We've seen countless photos of the Gernier with different dogs all over the country. Now that "Entourage" is over, perhaps Grenier should consider opening his own dog-walking service.
