My first officer the other day (shout out to Jamie Linderman) has a dog that has been blind since birth…they had to remove its eyes after an infection, so absolutely no visual input. He throws a whiffle ball with a treat inside and the dog finds it, spins to hear the different sounds in the room to orient itself, then comes right to him…I know, so amazing and cute…
