Some dogs tend to tear a lot more than others... if you have checked the fur and there is no irritation to the eyes check the environment... is it dusty where you live? or does someone in your home smoke?.... dogs do not normally tear as a result of food allergies... It happens more so with environmental allergies... some dogs react badly to cigarette smoke and some to dust.... If you have checked all of the above and it is neither one of these factors it is very possibly genetic...
Tearing is basically caused by tear duct irritation... Some dogs tear profusely while others don't tear at all... Check if the eyes are red... if they aren't then, again it may possibly be genetic... if you can deal with it its best to just leave it as it is but cleaning frequently to avoid further irritation(just use a cotton ball/facial cotton to wipe tears. you may wet the cotton with normal saline or water first if you prefer)... if you cannot there are many products out there to stop tearing but personally, i do not recommend feeding your dog with ANY pills unless completely necessary(as too many pills in a dogs lifetime will cause the liver to overwork itself)... one product that i've heard works is Health and Shine... It is a pill but cannot be given to the dog all their lives as the dogs body will become immune to it and the tearing will return...
My advice is to just leave it if you can deal with it... if you're worried you may bring your dog to the vet for a check first. :)
