Did you spot the heartbreaking detail in the Cambridge family’s sweet video?

The Cambridges are undoubtedly one of the most talked-about families in the world, with Prince William and Kate Middleton never failing to make news.

This week, it was the Duke and Duchess of Cambridge's marriage that got the world talking as they celebrated their 10-year anniversary.

Marking the day, Prince William and Kate Middleton posted stunning new portraits of themselves to Instagram. But it was their evening upload that made the biggest headlines, as the Duke and Duchess posted a home video of their family - and it's more heart-warming than a John Lewis advert.

Holding hands on the beach, laughing and toasting marshmallows - it's all there - and unsurprisingly, it's going viral.

'Thank you to everyone for the kind messages on our wedding anniversary,' the Duke and Duchess of Cambridge captioned the sweet video. 'We are enormously grateful for the 10 years of support we have received in our lives as a family. W & C'

While many focused on Kate's similarities to Princess Diana and Prince Louis' cheeky grin in the comment section, eagle-eyed viewers spotted a heartbreaking detail.

Featuring in the video alongside the family of five was their beloved cocker spaniel Lupo, who sadly died last year.

The Cambridges released a personal statement at the time, paying tribute to the 'heart of [their] family'.

As well as the home video, the Duke and Duchess also released two never-before-seen portraits to mark their 10-year wedding anniversary.

They later posted another photograph to social media from the recent shoot, captioning the loved-up snap: 'Taken this week ahead of the Duke and Duchess' 10th wedding anniversary'.
