We have an 8 month old jack russell/rat terrier mix pup. Yesterday he was very active playing ball most of the day and by evening looked like he could almost fall asleep standing up. We assumed he was overly tired. However, this morning he still seems to squint his eyes almost as if he is sensitive to the light. There appears to be no discharge from his eyes. We have a previously scheduled appointment with our vet on Monday. Do we need to go sooner?
