Typical fur for a Lagotto ?

Hi all,

We just got our 5 month old Lagotto girl a week ago. She has all the papers and is from a certified breeder. I was just wondering, looking at all the Lagottos online and I see that her coat is a lot more wavy and straighter than the typical Lagotto, at least on her back. It’s also quite rough. This doesn’t bother us a bit, we love her no matter what type of fur she has, just wondering if that’s normal.

Thanks .
