You can get a free Horse Brush in the Chapter 2 mission: Exit Pursued by a Bruised Ego. The Horse Brush will be given to you by the Stable owner upon purchasing a horse from him — this is all part of the mission, so go to the Exit Pursued by a Bruised Ego if you are having problems.
On the ground:
Move close to your horse and target it with the left trigger. (L2 on PS4) Press left on the d-pad and you’ll brush your horse. Keep pressing left to keep on brushing your horse continuously.

Where to find the best horse. You will find Lake Isabella in the western Grizzlies in the state of Ambarino — the snowy, mountainous area in the far northwest corner of Red Dead Redemption 2’s map. The white Arabian horse hangs out on the western bank of the lake.
After you complete (well, technically, just start) Hosea’s “Exit Pursued by a Bruised Ego” mission during Chapter 2, you’ll have access to stables in most towns you visit — they’re marked with a horseshoe icon on your map. Stables, as you’d expect, are where you go for your horses and horse-related needs.
You can unlock Fast Travel in RDR2 by upgrading your gang’s camp after the start of Chapter 2: Horseshoe Overlook. Note: You’ll need $545 to unlock the Fast Travel map. Go to The Heartlands to make an easy $500 or to Treasure Maps to make an easy $100.

No. You lose any horses Arthur had at the end of Chapter 6, even those stored in the stable. It may be possible to re-tame the white Arabian with John (I’ve heard that it respawns in the epilogue, but I’ve never tried it, myself).
