Um I'm usualy out at the ranch like 5-6times a week, so each of those day's I'll be grooming-but I have to groom like 6 different horses, so they don't all get groomed every time. The one horse who does get groomed every time is Shawnee, and she is veryyyy clean haha.
For her I use the shedding brush for a once-over, then go over with a thicker brush to get excess hair off, and then the third brush which picks up little dust particles. After that I brush out her mane and tail. The tail I braid the top half, which I rebraid every two days. (I'll include a pic!) I always clean out her hooves too. Her back two take longer because she is still sensitive aout her backside (mustang). I do a full bathe once a week.
Sounds like a lot but it's actually pretty fast if I do it regularly (because then she keeps fairly clean all the time). The longest parts of grooming ar usually feet and tail, just cause her feet get sooo dirty so easy and her tail I have to re-braid.
Oh! And for detangler, Mane and Tail spray detangler works wonders! I spray it on, let it sit for a sec, and can get any horse's tail detangled and manageable :)
