My Riley was having the same hair issues, that you are describing. and I have been using the fish oil, and it is making a world of differnce in his skin..but that HAIR!!!

...so just very recently I shaved it off...and OMG the differnce in what was underneath their,,:

...It is sooooo soft and nice now, I am soooooooo glad I cut off that puppy hair,Riley is 6 months old, and I think he is going to have silky hair, (going by the look and feel of what was under neath) and its cool to see what the color of the new growth is..that is my suggestion,,just shave it off,,or take him to a groomer and have them do it, its amazing the difference, no more mates or tangles, and he is so soft and shiny now,,but if you shave yours just make sure to keep him (or her) warm, I have been wearing clothes on riley ever since I cut his hair, just to be on the safe side, Ill include Rileys b4 and after pic,,you can clealy see the improvement in the coat,,and he dosent scratch hardly at all anymore.
