Every morning as well as throughout the day I clean my dog's eyes. To me the discharge is normal, just like humans, we need to wash our faces in the morning (get the sleep out of our eyes). As long as the discharge isn't yellowish or greenish... not an expert but that's my opinion....
I have to wipe away the "sleepy" discharge in my vizslas eyes every morning. Its now part of the daily routine. When I have a tissue in my hand and say "wipe your eyes" he sits and tilts his head up for me and once I have done the first one he turns his head for me to do the next.
I have never had another dog have have this so guess it must be something to do with certain breeds.
About a month ago we noticed daily discharge from our 11 month old vizsla's eyes. I just wipe it off in the morning, and maybe again during the day. I do plan to ask the vet about it next visit, but it does seem like noninfectious drainage so I bet it is normal. I think I would stay away from the disinfectant wipes as they would take away the normal flora as well, and may be irritating to the eye.
I usually scoop it out and don't let him eat it... early on he was getting toilet paper, pulling off the roll an eating it before we got to him. He had a few turds that were all paper after that. He sometimes gets a snippet down, but also has learned to leave the TP alone. Now it is paper napkins that seem to charm him.
I've had Wiley now for 6 weeks and have had to wipe the "eye goobers" from his face a couple of times a day since I brought him home. I asked the vet about it 2 weeks ago when he was in for his shots and said that clear discharge is perfectly normal. The only time you should worry is if it turns a green or yellow.
As others have said, it's just part of the routine now. I make him sit, put the palms of my hands and fingers around the bottom/side of his face and wipe the goobers off with my thumbs. He doesn't seem to fuss and actually seems to appreciate it.
