Meet the World's Tallest and Shortest Dogs! Gibson and Boo Boo. These are the extremes: the world's tallest dog Gibson (7 ft / 2.1 m tall when standing on his hind legs) has met Boo Boo (4 in / 10 cm high) the world's smallest dog in Sacramento, California for Guinness World Records Day 2007.
Generally speaking, the bigger the dog, the shorter the life. I have read that the dog with the shortest average life expectancy is the Irish Wolfhound...they live five or six years. Great Danes live six or seven years. As for small dogs, I know of Pomeranians who are 18 and 19 years old. Source(s): I work at a vet hospital.
