We have recently discovered that our dog has a problem. For the past week, Roxy has begun to look at the floor like she's seeing something; she'll even pounce at it. She's always been cross-eyed so we were wondering if maybe her vision has gone down hill or if there is another explanation for her behavior. I should also mention that she also does this when she's sitting on the bed or couch, so I don't think the problem is that she's hearing something. It's more like she sees her shadow and can't figure out what it is. If there is anyone out there with any suggestions or information on this please let me know.
