Replacement plastic strip

I'm trying to find a replacement strip for the plastic strip on a patio door, it is the strip between the frame and the actual glass on the outside of the door. This is a Pella door with the blinds in between the glass panels. My dog broke the plastic scratching at the door to get inside.
here are pictures of the piece that is broken. this goes all the way around the window and there is a 1/4 inch gap between the door frame and the window pane that this covers. it is a hard plastic but flexible. Not rubber. although rubber would make better sense.
