National Dog Day Foundation explains, "No one can win hearts like man's best friend and in honor of this bond between [humankind] and canine, Dog Day is celebrated. Take time to appreciate the love and value that dogs bring to our daily lives, and to do your bit for homeless and abused dogs the world over. Recommendations for ways to celebrate Dog Day range from adopting a dog from a rescue home to giving your dog a holistic spa treatment or even buying yourself and your dog matching t-shirts. The National Dog Day Foundation supports all breeds and varieties of dogs and discourages purchasing from unethical backyard breeders and puppy mills; instead, support reputable breeders or adopt from rescue homes."
