The Queen’s corgis (and “dorgis”, a cross-breed she kept) are probably the most well-travelled pets in history. Dotted through the rich photographic archive of her reign, there are pictures of courtiers manhandling the dogs on and off planes, and chaperoning them into royal cars. One of them, Berry, had a penchant for photobombing official photographs. When the Queen met England’s World Cup-winning rugby squad in 2003, he wandered into shot, raising a smile from the team. Four corgis appeared with her on the cover of Vanity Fair.
