Here is my Tennessee Walker's before and after grooming photos! I just curry the heck out of her every time I groom until at least 90% of the dust is gone, and I condition her mane and tail with Fructis Sleek-and-Shine leave-in conditioner. I bathe her only about four times a year. She eats a pound of Strategy Healthy Edge twice a day, and has 20-50mg per day of biotin, depending on how dry her hooves are, along with some loose mineral salt.
In Spring, she is also going to get some paprika for her coat. Otherwise she is out in the pasture all day with a muzzle on eating regular Fescue grass. At night she is in the roundpen because she is an easy keeper and blows up like a balloon if I don't watch it! She loves wet grass or fresh spring grass. But she'll eat every blade in sight if we let her.
**I must not forget to thank the difficult horses, who made my life miserable, but who were better teachers than the well-behaved school horses who raised no problems.**
