Simba’s happy place is in the car on the way to a campsite. On Good Friday, the goldendoodle and his human parents went to Oak Creek Canyon. Ruth and Wesley Wallace got out of the car to enjoy the view of the vista. Simba was out running with joy. “Simba came from Ruth, full blast right up to me and jumped, and then cleared the rock wall and cleared all the cliff,” the dog’s owner Wesley Wallace said with a chuckle.

Back in the spring, he was accused of deceiving viewers when he claimed, in his Netflix show Our Planet, that walruses were falling off Siberian clifftops as a result of climate change. This was shown to be untrue by Canadian biologist and mammal expert Dr Susan Crockford, who described the abundant scientific literature, dating back many decades, showing that walruses have always taken to the land, and even fallen from clifftops.

Two skeletons dating from the Dark Ages of around 750AD have been recovered and a stone with a carefully chiselled cross has also been found.
