So did his dogs, of whom he had many: Thunder, Moretto, and Lyon, to name a few. The best known is Boatswain, whom Byron nursed through rabies to no avail, as there was no cure for it at the time. The inscription Byron placed upon Boatswain's tomb is well known, but worthy of repeating:
Near this spot
Are deposited the Remains of one
Who possessed Beauty without Vanity,
Strength without Insolence,
Courage without Ferocity,
And all the Virtues of Man without his Vices.
This Praise, which would be unmeaning Flattery If inscribed over human
ashes, Is but a just tribute to the Memory of BOATSWAIN, a DOG Who was born at
Newfoundland, May, 1803, And died at Newstead, Nov 18th, 1808.
The poem Byron wrote in his dog's memory is high flown in its elegance, but sincere. Read it here. There's an excellent page on Byron and his pets here courtesy of his home, Newstead Abbey.
