There is a girl at my barn who has a paint that has an all white tail, so she will braid it and then she folds it over and wraps vet wrap around it. It's basically what they do to mare's about to give foals, but it works. She takes it out when she rides and then she will brush it out and add conditioner and then put it back up.
Thankfully I have a dark horse, with a black tail. But on his little bits inside his legs, under her bottom.. on the back of his legs.. he's almost palimino! I use 'Dung Away' .. its a formula that...
Dung Away 500 ml
Formulated to help eliminate yellowing manure stains and grass stains. It can be used as part of general shampooing and show preparation, or for spot cleaning last minute stains."
Can buy it from Sponsored Listings .. not sure if that's avaliable in your country? But at least there is a product out there!! Maybe you could find something similar ?
I braid Kings tail, then we put MTG on the top of the tail (to grow it), last is we put the tail in the sock and tie the sock to the tail. It looks really pretty when its out of the sock and unbraided. :)
Ok so I'm on the other side of the world to you guys and no snow etc. But tails get pretty revolting here too!
I am a tail nazi, they have to be thick, shiny and tidy.
So my guys all get their tails bagged 24/7 with waterproof, zip up tail bags. They come off when I ride, get a light brush with a body brush, and then straight back in bags. I wash tails once every month, shampoo thoroughly, condition and leave the conditioner in for at least 10mins. Run a wide toothed comb through the tail in sections starting frrom the bottom and working my way up. Rinse out. Leave to dry and then spray with No-Knots or Cowboy Magic which repel light dirt and help to keep the tail tangle free.
My tails are always kept trimmed and squared at their base, cut off just about the fetlock joint. I don't like tails longer than this or not squared off, they look ratty!
