I was just holding Cocoa and I've gotten a bit concerned. He sneezed twice in the duration of an hour, and their was a clear wet substance(like water) near his nostrils. I wiped it off and it doesn't come out unless he sneezes. Is this nasal discharge a sign of illness? He is maintaining a healthy weight and coat, he's eating and drinking, and his eyes are clear. What does wheezing sound like? I'm a little scared because I don't want it to get so far out of hand that he dies. I;m afraid that if I wait any longer it will grow out of control.
