Sayas eyes seem to be looking weird. Her left eye is normal but her right eye's pupil is dilated. It is really dilated. Any ideas why?

When was she spayed?

She was spayed yesterday. Her eye looked awful after some advice I contacted an emergency vet and he told me to wait it out before bringing her in. He said that it could be related to the anesthesia. Her eye is much better now. She still has no energy but I definitively see some improvement. Her appetite is back

I was wondering if it could be the anesthesia, I had a knee done in Feb, and it took me a few days to see correctly, never happened to me before.

She could be kinda out of it for a few days, that's pretty normal, its quite the surgery!

Should I expect a change in attitude? Also approximately how long will she be like this, I cant believe I actually want her to get her energy back

I've heard people say their dogs rebounded pretty fast after getting fixed, but when Danzig got neutered, he was a wreck for a few days. When he first came home, he whimpered so bad it made me cry. I kinda think he had a bad reaction to the anesthesia. But after a week, he was back to be his usually self.
