From what I understand, both dogs and cats have poor "static" vision but can spot minute changes very, very well. A squirrel has a very specific gait and movement style which they can spot very well. If your dog saw a photo of a squirrel from 100yrds away, I doubt it would heed much attention to it.

My dog can also spot food on the cement sidewalk from far away, too far to be just the smell.
