The ‘Quarter Hounder’ is being released in honour of National Burger Day.

Smith & Whistle, a bar in London’s Mayfair, is offering customers’ canine companions the chance to sample a one-off doggy burger for pampered pooches.

The burger will be available for good boys (and girls) from Thursday 23 August for one week only, so pups can tuck into their own nosh while their owners enjoy a human-friendly version.

The Quarter Hounder is a collaboration between David Jackson, a specialist in canine nutrition, and chefs at Smith & Whistle.

It was created to be as nutritionally valuable as possible but still delicious, and features a lean chicken breast sandwiched between cooked sweet potato slices instead of a bread bun.

The burger is garnished with kale and tomato, and an added slice of cheese is optional.

Each Quarter Hounder is completely free as long as you buy a human burger at the same time.

Smith & Whistle is a dog-friendly bar, and its location opposite Green Park means that dogs and their owners can work off their burgers with a leisurely (or not so leisurely) stroll.

It also offers a permanent ‘dogtail’ menu – a speciality selection of drinks just for pups.

The bar manager of Smith & Whistle, Bruno Castro, says: ‘We were delighted with the success of our “dogtail” menu in April and have loved welcoming so many pooches through the doors of Smith & Whistle.

‘The popularity of the dogtails highlighted the demand for places that really go above and beyond to cater for man’s best friend and so we’re excited to be adding a new item to our menu for them in celebration of National Burger Day.

‘We’re confident the Quarter Hounders will go down a treat.’

If you want to purchase a doggy burger on its own, the Quarter Hounder will set you back £8.

With National Dog Day approaching on Sunday 26 August, it’s an excellent time to spoil your four legged friend.
