Yes to Miracle Groom. I am a big fan of feeding properly and proper grooming to get the coat to shine and lay down nicely but sometimes ya gotta cheat! Long winter coats are hard to keep clean and neat but this stuff does a good job of getting rid of poop stains and detangles a mane and tail without making it slippery or oily. Sheets/blankets keep your hard work to a minimum, too.
