Pelorus Jack was the name of the two bulldogs who were mascots of the Royal Navy ship, HMS New Zealand, from 1913 to 1919.

[1][5] During a port visit to Johannesburg, South Africa, a ceremony was held where Pelorus Jack was presented with a studded collar.

His loss is mourned by the men, who had become very attached to the dog, as he was on deck barking at the shells all through the two engagements, and he was to have been presented with a medal.

[8] The New Zealand History website states that it's not known how Pelorus Jack reached the top of a funnel "but his demise was probably not accidental".

[10] Pelorus Jack was ranked leading sea dog, serving during the Battle of Jutland, and was trained to take refuge when he heard guns firing.

His death was reported: The mascot of the battle-cruiser New Zealand, the bulldog "Pelorus Jack," was handed over by Captain Leggett to the Deputy-Mayor as a gift to the citizens of Auckland.

In the meantime its silver harness and its gold collar, have been taken possession of by the Superintendent of Parks, who will eventually be the custodian of the dog.

Pelorus Jack was presented with two collars during his service, one is part of the collection at the Auckland War Memorial Museum in on display in the permanent exhibition, 'Scars on the heart'.
