Few companions have shaped human history quite like the dog. From loyal working partners and trusted guards to beloved family pets, dogs have earned their reputation as humanity's best friend.

International Dog Day, celebrated annually on 26 August, is an opportunity to celebrate every dog, regardless of breed, age or background, while also recognising the countless rescue dogs still waiting for a loving home. It's a day to appreciate the joy, loyalty and comfort these four-legged friends bring into our lives, from being a companion during a long walk to greeting us with boundless enthusiasm.

Where's toasting our canine friends with a Red Dog Smash, but you may prefer a French Bulldog, or even a Old Dog New Tricks.

The day a new colour transformed science

In 1856, a teenage chemistry prodigy, William Perkin, accidentally invented a new colour. His discovery, mauveine, which he patented on this day, would go on to change the world, in this case quite literally.

Before Perkin's discovery, all dyes were natural - made from roots, leaves, flowers or, in the case of purple, sea snails. Now, for the first time, fabrics could be dyed in predictable, lasting shades. Best of all, Perkin's discovery inspired other bright young Londoners to take up chemistry and develop medicines, photography and much, much more.

We are toasting Perkin and his purple with the mauve-coloured, violet-flavoured Parma Violet Spritz.
