Tino has a wavy panel on his back. I think it looks cool. I hadn’t noticed it before this winter. I wonder if it was always there and I just didn’t notice. I looked through some old pictures and I don’t see it, but I don’t normally take pictures of his back. if it’s just a normal thing that happens to dogs, then I think it’s pretty cool that he has a wavy panel on his back now. It’s very sporty. 
The first three pictures are from today and the last two are from years ago
