Lost brown canvas backpack with rainbow and small dog patches containing a blue water bottle and sketchbook in Old Town Fort Collins.

I lost my brown canvas backpack while walking around Old Town Fort Collins last Saturday. It has some unique patches on it, including a rainbow and a small dog. It also contains a blue water bottle and my sketchbook with artwork inside. I must have set it down while grabbing a coffee and walked away without it. Please let me know if you see it!
