Happy National Dog Day!
There's few things a Hollywood star can count on more than their furry friends. Dogs have been there for our favorite celebs through thick and thin, great for Instagram likes, workout buddies, and always there to keep a good secret.
It's no wonder the stars came out on Friday to pay tribute to their four-legged companions. Check out a few of our favorite National Dog Day pics below.
John Stamos took to Instagram on Friday to share an adorable photo of himself swimming with his dog, Frieda, though pics like these aren’t uncommon on the 53-year-old actor’s page. Stamos’ Instagram is full of cute puppy pics of Frieda and his other dog, Linka, who died last week. 

Kate Upton has somehow passed down her photogenic genes to her dog, Harley! The model and her pooch shared a cute smooch in celebration of the holiday on Friday, and couldn’t look better while doing it.
Gina Rodriguez and her pup Casper have grown so close, they're starting to look alike! The Jane the Virgin star and her furry friend showed off their Snapchat filter mastery on Instagram.
Russell Wilson took a break from newlywed life to gush about his dogs, Prince and Naomi. "Best Dogs Ever!" Wilson wrote on Instagram, along with a snap of his two great danes looking out at a lake. "Early Mornings Sitting on the porch!"

While many celebs paid tribute to their dogs, Zac Efron was remembering his dog, Puppy, in a different way. The 28-year-old actor announced that Puppy had died with a touching post on Instagram on Thursday night.
"Through thick and think you’ve always been my best friend. I'll see you at the finish line, RIP Puppy Efron," he wrote.
