I give my dog a rub down after a work out, mainly because it's what I was thought to do lol. I also use a green alcohol based muscle rub designed for horses but I dilute it with apple cider vinigar and a drop of water, this changes is from the thick liquid it is to a watery liquid and then I put it in a spray bottle and spray it on before rubbing the dog down. I also spray the inside of there dog boxes with apple cider vinigar.
