I'm a first time Bernese owner. We got the little guy (not so little now...) fairly recently. He's about 18 weeks old now. He no longer has that soft, puffy hair look that most bernese do. His hair is all wavy and almost appears to be greasy, even after a bath. Is there any thing I can give him to get his old hair back to how it was before? I'm a little confused as to why he's like this. It's not really the biggest deal, but nobody else in his bloodline was like this. His father was one of the top show dogs in the US and his mother had a flawless coat. Is this perfectly normal? Is there something I should be concerned about?
