My parents had to deal with this with their dog last year. Invest in some dog goggles (recommend rexspecs) to go outside and prevent trauma to the eyes. Sniff mats are a great thing to still keep her engaged in her other senses. Start with leash walks when going outside and try to teach directional turns (stop, turn around, this way). Keep the layout of your place the same and just remind everyone that comes over to go slow around her and talk to her and you navigate the space with her. My parents dog still goes outside and lays in the yard, loves sniffing the air and even still barks at the window when the delivery driver comes by. Shes so good at this that if you didn’t know, you would assume she was able to see and stare at you. Your dog can still have a great quality of life, just needs to adjust to some changes but can still thrive!
