1. Your 24-year-old horse is akin to a…

A) 72- to 96-year-old human.

B) 52- to 76-year-old human.

C) 32- to 56-year-old human.

T / F

T / F

4. Most experts agree a horse can be considered geriatric when he reaches what age range?

A) 15 to 17

B) 16 to 18

C) 18 to 20

HOW’D YOU DO? (Answers below.)

1. A is correct. Every year of a horse’s life translates into roughly 3 or 4 human years, so your 24-year-old is approximately equivalent to a 72- to 96-year-old human.

2. T is correct. Older horses have less-effective immune systems, which means they are more susceptible to illness and parasitism, plus slower to recover from both disease and injury.

3. F is correct. The actual estimate is 30%. Older horses are at a considerable increased risk of developing endocrine disorders, such as Cushing’s disease or insulin resistance.

4. C is correct. An 18- to 20-year-old horse is considered geriatric…but it doesn’t necessarily mean he’s too old to be ridden or even competed. The answer to that is…it depends! (On what? See below.)
