As you sort after answers to lots of questions about Chihuahuas such as “Why Are Chihuahuas Eyes So Big?”, it’s alright to also note that many eye diseases that affect this specie of dogs can be inherited; if your vet doesn’t discover them in time, some of them may even result in blindness. Chihuahuas and many other small-breed dogs frequently have the same eye health issues. One of them is the crying eyes’ scars and watery eyes.

Epiphora, which literally translates as an excess of tears, is the medical term for watery eyes. A hereditary abnormality that forces the eyelid or eyelashes to bend inside rather than outward is possibly the source of this ailment. Shar Peis, Labradors, Shih Tzus, Cocker Spaniels, Bulldogs, Dachshunds, Pekingese, and Chihuahuas are some of the breeds that are prone to inheriting such disorders as well as having watery eyes.

Your Chihuahua or other dogs may squint, be inflamed, or have red, swollen eyes in addition to having watery eyes. Watery eyes can also be a symptom of other illnesses, such as facial injuries, tumors, infections, sinus problems, congenital anomalies of the eyes or eyelids, and dirt in the eyes.

There usually isn’t anything else wrong if your Chihuahua has had wet eyes their entire life. If your dog’s eyes suddenly get wet, you should take them to the doctor to make sure they haven’t been inflamed or scraped by debris. 

Since they are closer to the ground and more exposed to moving dust, small, energetic dogs are more likely to have debris in their eyes. If your dog displays other symptoms or if the discharge coming from their eyes is yellow, green, or bloody, call your veterinarian.

The recessive gene that results in blue eyes is present in only 5% of Chihuahuas, making them quite rare.
