Miko has needed to be shaved before for too many matts. Sometimes a groomer can salvage it (don't wait, go find a groomer now) but sometimes its just too much. I am definitely a bad mommy and don't brush as often or as thoroughly as I should. I have given up though at this point and plan to keep Miko in a shorter puppy cut. I think he looks adorable either way and truly I don't have the time or the energy and I know he couldn't care less (and probably prefers to be in a shorter cut anyways).
