A mom and dad, along with their two little girls, sit with their favorite furry family member, petting him lovingly. It's a touching way to celebrate a special pup in somebody's life on National Dog Day, August 26th. With four legs and one very big heart, our pooches are the ones who are there for us, giving us unconditional love, on good days and bad. So as we set aside a special date to recognize them, this is the perfect card to send to your favorite canine lover.
