Adam Clark and his partner Kim Mcguire, bought Ollie, a lagotto Romagnolo, as a surprise for their daughter Alicia.

The puppy unearthed 15 gold sovereign pieces, which are estimated to date back to the 19th century, during the walk near Blackpool on March 30, The Times reports.

Mr Clark took the gold coins to be examined by Chards Coin and Bullion Dealer, who valued them at £5,943.96.
