I have noticed that my 5 month-old Muffin is getting more and more dandruff. I give her a bath once a week using the CC hair system. She gets brushed FAITHFULLY every night. She eats Royal Canin dry puppy food with a wee bit of Wellness canned mixed in. Her coat seems to be dry and I can't figure out why. I did read somewhere that I could give her a teaspoon of olive oil mixed in with her food once a day. Does anybody else do this or do you have other tricks to keep the flakes away?
