I really pefer not to change a horses name. 4 out of my 5 previous horses retained its name when bought and the oldest was 8, youngest 1).
I have lived with a Dolly, Eagle, Sarah and Beauty. I didn’t like any of their barn names or reg’d names for that matter, but they really weren’t too bad.
The only one that I changed was Tucker. I had a 3 yr old son with a lisp. I didn’t want him telling his JK classmates he had a horse named “F***ER”. So Tucker (4yr old Bay 14.1 QH x ?Pony - super cute thought kids would enjoy pony rides and mom long trail rides) became Hunter (named for the bay pony I used to ride in lessons when I was 12.)
BUT!
I have noticed that most Arabian have either traditional names (which is not a personal favorite) or really hokey cute names ie. Buffy, Sweety, Star etc.
Having lived with “Hellllllooooo Dolly!” for 5 years.
My top three choices for my next horse have hard to live with names. Sigh I need a break from babies but hesitate at the thought of changing an 18yr old’s name.
