I posted a question on here a while back about my girl's coat. Well thanks to you all, I have changed her diet to an all meat 6 star dog food and her coat is looking better than ever. But, in my discussion someone mentioned that I should use some oil when I bathe her. What kind of oil and how do you recommend I do this? Pour it right on? Dilute it? How much? Or, did I read this way wrong?
