Horse
Depending on breed, management and environment, the modern domestic horse has a life expectancy of 25 to 30 years. Uncommonly, a few animals live into their 40s and, occasionally, beyond. The oldest verifiable record was "Old Billy", a 19th-century horse that lived to the age of 62. In modern times, Sugar Puff, who had been listed in "Guinness World Records" as the world's oldest living pony, died in 2007 at age 56.
Gordon Setter
Although not as prone to hip dysplasia as many of the larger breeds, Gordons can suffer from the condition. Other health issues can include hypothyroidism, gastric torsion (bloat) and eye diseases such as progressive retinal atrophy (PRA), and cataracts. Life expectancy for the breed is generally about 10 to 12 years.
