Max is right in the midst of a heavy teething stage right now. I would blot the wet area with tissues for the time being - as long as you aren't worried about an eye infection and as long as he isn't rubbing his eyes on the carpeting/bed/ground.
If he is rubbing his eyes, you might want to get him seen by the vet to prevent corneal scarring. If you aren't sure, it would be best to have the vet take a look. At one year of age, if Max still has watery eyes you might want to take him to a veterinary ophthalmologist and/or a dermatologist to diagnose chronic problems.
My India had teary eyes as a pup. We waited til she was one year old (per the vet), then the vet diagnosed entropian, which required a laser procedure to correct.
Chocolate's breeder scolded me a bit after the fact, asking why I didn't take India to a veterinary ophthalmologist. I didn't know any better at the time, but India's eyes are fine now! Now that I know better, I would go to an ophthalmologist if possible.
One of the veterinary dermatologists at Ohio State University helped India by diagnosing a yeast infection caused by food allergies. We found that a chicken allergy and a grain allergy cause her to get yeast around her ears, eyes, and mouth (it is smelly) so with a diet change to either commercial frozen raw lamb or venison and millet kibble she is perfectly fine now.
Sorry for the long post, but as you can see - watery eyes can be caused by teething or by other chronic problems that need attention!
