Mojo, Does this describe you little one. I know that Charlie is the size of Diesel and weighs 6 pounds. His hair does seem dry and brittle. Not very soft. It also says pigment changes. That would explain the white spots all over his nose and eye rims. i am going to TRY to pass this on to my granmother. She thinks her vet can do no wrong and more than likely will tell me I don't know what I am talking about. So we will see. I think it is worth checking on tho.
