I myself was going to try insulated dog blankets that were on sale but I can't remember which Co. sent the magazine. I also found a site for patterns for foal and horse blankets by just googling it. All this info was on my other computer that crashed and died so I don't have the links anymore. Thankfully my daughter sent me her adorable foal blanket that is very, very adjustable, waterproof, and I have another fleece foal coat to go under it so that I didn't have to try the dog blankets. I was going to order the one with the piece that goes between the front legs and velcro's up the either side. I need to find out where she got this blanket, because I haven't seen one like it before and just love it.
