I have posted a video of Hooty, one of my foster dogs, here:
Hooty, the blind flying dog - YouTube
Hooty has some kind of vision impairment, but I don't know what kind. I thought maybe someone else on the forums might have some experience with vision loss. Hooty gets around fine and seems to have some vision (maybe he just sees shadows), but he doesn't seem to see me when I am standing right in front of him. If you notice in the video, I am standing about 6 feet from him, but he looks around and then sniffs the air to find me.
If you didn't see him bump into things occasionally, you would think he is a normal dog, especially when you see him fly through the air! I have noticed that he has a red cast to his eyes, too. He will be going to the vet next week, so maybe we will get some answers then.
