In honor of National Dog Day, we asked our Facebook fans to send us photos of their favorite canines, and as always, they didn't disappoint. From service dogs and canine athletes to cuddle buddies and Ewok lookalikes, their submissions run the gamut of what it means to be man (or woman's) best friend.
Check them out in our gallery below, and don't forget to join in the celebration by sharing a photo of your best furry friend on our Facebook page!
Happy National Dog Day!

Jakka
Finally! Proof that Ewoks do exist! Jakka, a Lhasa Apso, is his owners' "biggest source of joy and entertainment." With that cute mug, we can definitely see why.

Calyx
Calyx, shown here at 4 months old (left) and 9 months old (right), is a German Shepherd rescue who was adopted by his foster family when he was just 7 weeks old. His owner says he adores his doggie siblings and playing in the grass. But he's a total fanatic when it comes to water.

Marley
This happy girl is named Marley. Her owner found her abandoned in a trash can when she was only 4 weeks old, and they have been inseparable ever since. Now 3.5 years old, Marley is "my reason to get up out of bed every day," says her owner. "I love my girl more than anything in this world!"
