Why do dogs eyes water?
Dogs' eyes can water for a variety of reasons, some of which are normal and some of which may be a sign of an underlying medical condition.
Normal reasons for watery eyes in dogs:
* Allergies: Just like people, dogs can have allergies to things like pollen, dust, mold, and food. When a dog is exposed to an allergen, their eyes may water, become red and itchy, and they may also start sneezing and licking their paws.
* Conjunctivitis (pink eye): Conjunctivitis is an inflammation of the conjunctiva, the clear membrane that covers the white part of the eye. It can be caused by a variety of things, including allergies, bacterial infections, and viral infections. Dogs with conjunctivitis will have watery eyes, red eyes, and may also have discharge from their eyes.
* Foreign objects: If a foreign object gets into your dog's eye, it can cause irritation and watering. This can happen if your dog is playing in a dusty or sandy area, or if they get something in their eye from a plant or tree.
* Epiphora: Epiphora is a condition in which tears overflow from the eyes. It can be caused by a variety of things, including allergies, conjunctivitis, and foreign objects. Epiphora can also be caused by certain anatomical abnormalities, such as a narrow tear duct.
Medical conditions that can cause watery eyes in dogs:
* Glaucoma: Glaucoma is a condition in which the pressure inside the eye increases. It can be a very painful condition and can lead to blindness if not treated. Dogs with glaucoma will have watery eyes, red eyes, and may also have cloudy eyes and dilated pupils.
* Dry eyes: Dry eyes is a condition in which the eyes do not produce enough tears. It can be caused by a variety of things, including autoimmune disorders, medications, and old age. Dogs with dry eyes will have watery eyes, dry eyes, and may also have red eyes and squinting.
* Keratoconjunctivitis sicca (KCS): KCS is a severe form of dry eyes that is caused by an autoimmune disorder. It is a progressive disease that can eventually lead to blindness. Dogs with KCS will have watery eyes, dry eyes, and may also have red eyes, squinting, and pain.
If your dog's eyes are watering, it is important to take them to the vet to determine the cause. Some causes of watery eyes are harmless, while others can be a sign of a serious underlying medical condition.
