Dog question for you dog people:

[Nataku]

Aussies are a fun breed. I just recently fostered a deaf one for a few weeks, although she had normal vision. The only aussie I can remember ever meeting with starburst pupils was at a show some years ago (not being shown, just one of the other dogs the breeder had brought along with them in her RV). She told me the dog was light sensitive, and I was inclined to believe her because for all the energy the dog had, it would not leave the RV willingly during daylight. If forcibly picked up and taken outside with the sun out, the dog would squint its eyes shut and navigate by sound as best it could. She told me the dog had developed the interesting habit of never going to the bathroom during daylight hours, because it didn't want to go outside during the day, but being house-broken, it just waited inside until night, at which point in time it would go outside and be a normal dog for all other intents and purposes.

Now, I don't know if all dogs suffering from starburst pupils have this light sensitivity problem. I've only met the one and that's hardly enough of a sample group to draw any conclusions from. Were I you, I'd simply observe the dog closely the first few weeks and see if there is any tendencies for the dog to prefer certain areas and avoid others, or certain times of the day when they are or are not more active.
