Saturday is National Dog Day, an annual observance to honor pups and dogs who play an important role in a human's life. This day is marked to spread awareness about rescue dogs.

Started by pet expert Colleen Paige, National Dog Day is held every year on Aug. 26 — the anniversary of the day she adopted her first canine. On this day, show some extra love to the best friend and also share some quotes with the pet parent you know.

"Millions of dogs are killed each year because they're simply unwanted. They're unwanted because no one realized how to properly care for the demands of the breed. They're unwanted because they were bought as a Christmas gift for a child that didn't keep their promises about caring for the dog...unwanted because they shed too much...unwanted because they bark too much. UNWANTED...simply because someone changed their mind. All a dog wants to do is love you and be loved by you. Dogs are amazing, courageous, sensitive and sentient beings that deserve compassion and respect. Please consider bringing what was once considered 'unwanted love,' into your heart and home on National Dog Day!" Paige wrote.
