This year there will be more than one million advent calendars for pets on sale in UK supermarkets, but only 400,000 Christian alternatives.

Out of the 20 million calendars produced for human consumption, less than 400,000 carry any mention of the Nativity, with only two brands providing Fairtrade chocolate and only one donating proceeds to charity.

David Marshall, from the Meaningful Chocolate Company who manufacturer The Real Advent Calendar, said: "Stores are happy to cater for pet owners, but don't think Christians want to give children a quality Advent calendar that connects with the Christmas story - it's barking."

The Real Advent Calendar is the UK’s only Fairtrade, religious, charity option. 

It is a fun way for parents, grandparents and godparents to share the Christmas story. 

Behind each of the 25 windows there is a Fairtrade chocolate star and a few words from the Christmas story, along with a booklet to read, keep and enjoy.

As well as celebrating the true meaning of Christmas, the calendar makes a charity donation to The Funzi and Bodo Trust from every sale.

More information about the Meaningful Chocolate Company can be found on their website. 

The Real Advent Calendar costs £3.99 and can be purchased from Tesco and online retailers.
