Remember, white vetwrap for light tails, and don't do pregnant mares with red, you will give yourself many heart attacks, ask me how I know.[/QUOTE]
I use brightly colored vet wrap on all but one of my tails because I have only 1 white tail, but the one color I refuse to use for any reason is red. I totally get the no red on pregnant mares.
Guardtex is actually my favorite wrap but it's a lot more expensive than vet wrap. I also like to put a few hay strings in when I'm wrapping, let the ends hang free so that the horse can swish flies if he needs to. We also keep our tails up year round.
