Baker originally acquired Big Red as a trail riding horse for a couple of years before he transferred over to helping people.
In his racing days, Holiday had 23 career starts, greeting the judges first on one occasion as well as four other minor placings.
He started his racing days with trainer Trevor Whittington on the Gold Coast before eventually running his last couple of races in North Queensland with Townsville trainer Bill Kenning in early 2015.
Baker thinks the son of Hotel Grand has a perfect attitude to be a therapy horse.
“He has a very calm temperament,” she said.
“With other horses he used to be quite full on and aggressive towards them, even a bit bossy, but with people, he has never even pricked his ears up.
“People is his thing, he has such a nice, calm temperament.
“He has strong boundaries as well, but he will let you know in a kind way.”
While Big Red is not overly fond of other horses, he has found a little friend to spend his days with.
“In the paddock, his best friend is a little tiny mini called Ra Ra, who is his work buddy as well,” Baker said.
“He does not have much time for other horses and when Ra Ra came along, the other horses used to pick on her so she found that standing underneath Big Red was the safest thing to do.
“Their friendship started like that.”
As well as his work as a therapy horse, Big Red has recently started his jumping career with Baker’s 12-year-old daughter over the last few months, which is an activity the former racehorse thoroughly enjoys.
