Blind help

[DeepfriedPizza]

I have sliding patio doors which is my only exit/entrance to the back garden.
I need blinds and they need to be two separate, one for each glass panel but I am hitting some snags.

I can't have vertical as my dog gets tangled in them, even when fully opened/

roman/roller would have 2 seperate chords therefore would have one dangly bit in the middle, wouldn't I?
I can't have the fitted into the glass as the doors slide so can't add any width.

I am not sure what that leaves me.
Any advice?

You can now buy roller blinds without any side pulley. Just pull and push up using bottom of blind.

ah, I think that's what I need. thank you

Although how would I fit two blinds together, they are usually attached to the frame of the window aren't they. They'd need to be attached outside the frame?
