It's 25..and if you contact AQHA saying that the horse is 25 and still alive they will update his records.
Here is your horse's pedigree from the AQHA records. PEDIGREE RECORD © 2008, AQHA. All Rights Reserved.
But here is the information from America's Horse Daily AQHA Record Update – America’s Horse Daily
On January 1 of each year, all horses turning 25 are listed as deceased in AQHA’s database unless AQHA is notified that the horse is still alive
. It is important to keep your records up to date and to notify AQHA of your elderly horse’s status.
So, if your horse is 25 this year, simply e-mail firstname.lastname@example.org
with a current photo of the horse, its registered name and your contact information
Because the average life span of a horse is 25 years, horses over the age of 25 are listed as deceased to help AQHA keep a current and accurate count of the population of horses.
Because the inventory of horses in each state determines the number of AQHA directors allotted for that state, it is important for the Association to have the most accurate total population of horses, says Tammy Canida, director of registration operations.
To make sure that your senior horse’s status stays active, send a note and current picture of the horse, along with his registered name, to AQHA’s Registration Department. You can do this at any time.
