The Queen feeds her beloved corgi pooches cheap dog food which costs 45p over posh pet grub, a documentary has claimed.

Her Majesty is a well-known dog lover and started her long infatuation with corgis back in 1955.

But, as of 2018, the Queen now only has two “dorgis”, crossed between a corgi and dachshund.

Her last purebred corgi, Willow, died at Windsor Castle in 2018.

The Queen reportedly does not want either Vulcan and Candy to outlive her and has asked for them to be stopped from breeding.

She is known to pamper her pooches.

So it might come as a surprise to learn Her Majesty feeds her dogs budget grub from one of the UK’s most-popular retailers Tesco.

The Queen has always been a huge dog lover

Broadcaster Daisy McAndrew made the revelation on Channel 5 documentary, Inside Waitrose.

While analysing some of the dog food at one of Waitrose's Royal Warrant stores, she picked up a tin of Forthglade dog food and listed off ingredients fit for a dog-prince.

Daisy told Channel 5: "The ingredients are beef, wild boar, apple, parsnip, carrots, and seaweed.

"Now that list of ingredients is more expensive and better than people feed to themselves or their children.

The Queen reportedly feeds her dogs cheap Tesco food

"This is probably the poshest of all Waitrose products."

"We know the royals particularly are huge dog fans, they all have dogs.

"However, we do know that the Queen feeds her dogs Tesco basic dog food."

Cans of Tesco's basic dog food fetch for just 45p a can, whereas Fairgrade goes for between £1.49 and £11.99.

Waitrose was awarded a Royal Warrant to supply groceries, wine, and spirits to the Queen in 2002 and, as of 2011, to Prince Charles and Camilla, Duchess of Cornwall.

The Duke of Edinburgh withdrew the Royal Warrant from Harrods in December 2000 after Mohamed Fayed accused him of masterminding the car crash in which Dodi Fayed, his son, and Princess Diana died.

Warrants are awarded as a mark of recognition to people or companies who have regularly supplied goods or services to members of the Royal Family.

Food manufacturers and suppliers with a Royal Warrant include Fortnum and Mason, Bendicks of Mayfair, Cadbury, Nestle, Kellogg's, Weetabix and Dewhurst Butchers.
