If you like the long coat look, then I think it is worth it. I am growing out Josh's hair. I like to give him messages and treats to make the grooming a good experience. There are some grooming sprays to help get out knots in dog's fur. I think this link How to Brush Matts out of Dog Hair - wikiHow might give you some advice on how to comb or brush your dog's hair. 
Yeah, this post is my 1,000 post.
