Will the white Arabian Respawn if I lose it?
Yes it will come back, but you have to leave the area far enough. I rode back to Watson's Cabin and when i returned to Lake Isabella, the horse was there again on the same spot. Thanks!
The horse respawns when it dies.
Yes, as long as you sell it before you finish chapter six you can re-tame it with John.
Keep in mind that there seems to be only one white Arabian horse in the game, and horses can die — permanently — if you're not careful.
West of Lake Isabella. This is the only location it can be found, and it is found by random chance. You may have to leave and return to this area a few times before it will appear.
Of all the Arabian Horses, The White Arabian Horse is the only elite horse that can be found in the wild instead of having to be purchased, saving you a thousand dollars! You can find this special horse on the northwestern side of Lake Isabella in Grizzlies West. To start, Fast Travel to Strawberry and ride north.
Rose Grey Bay Arabian (The Best Overall)
She features better Health and Stamina than the other two Arabians. Although she's also very expensive—going for $1250 in-game dollars.
Does the white Arabian horse reappear in RDR2 if it dies? Yes. Like every player in Rdr2, I can get a bit *rough* with my horses. Naturally, the honorable Arthur hogties the two, and goes to claim the reward.
The Arabian is a particular breed of horse in Red Dead Redemption 2. They are classified as Elite Superior Horses. Our guide will tell you everything you need to know about the White Arabian Horse location in RDR2. This Horse Breed features three different coats, and are extremely high tier horses.
The Arabian Red Chestnut is a Superior breed of horse with great handling, speed and acceleration stats. It will serve as a meaningful stopgap between the horse you start out on and one of the best horses in the game, which you'll hopefully be saving up for.
Is the black Arabian better than the white?
The Black Arabian is the best horse in the game, with it being a slight upgrade on the White Arabian. It will definitely be a major boost to your efforts in-game, and you should definitely add it to your stable if you have the chance.
The White Arabian is available to locate and tame during Chapter 2, and with the right upgrades, you can boost its natural stats even further.

Yes, it will respawn - unless they patched it away ;) I had my Arabian die two times and always found another near Isabella Lake.
Speed, endurance, agility, and loyalty were prized among the Bedouin people—only the best horses were kept. Food was scarce and a “hard keeper” would not have survived in these conditions. Therefore, today, Arabians are generally known to be easy keepers.
What happens if the giant horse dies Botw? It will respawn with the next bloodmoon. You may want to take another horse out at a stable, or tame one, just to be sure the game isn't still tracking the original giant horse.
The rarest horse in Red Dead Redemption 2 is the Legendary White Coat Arabian. Once you break the horse and it stops bucking, you'll need to work on taming it.
As we mention below, you'll want to lasso the White Arabian as soon as you see it, climbing off your horse while holding the rope, and working your way steadily towards the horse, calming it with Square/X as you go.
