The sunlight that dogs are exposed to is not as dangerous to them as it is to us humans. Robert English, an eye care veterinarian, notes that most breeds of dogs are relatively safe from direct sunlight because of their heavy eyebrows and deep-set eyes.
However, for some puppies, sunglasses may be more than just a fun accessory to look good.
While it’s not known whether the sun’s rays can cause eye disease in dogs, they can make some physical conditions worse.
Chronic superficial keratitis (often called pannus keratitis) is an autoimmune disease of the cornea that can cause Vision loss in dogs. Like other autoimmune diseases, it causes the immune system to attack healthy cells. If left untreated, severe scarring can occur on the dog’s cornea. This disease is usually not painful, but it can greatly affect a dog’s quality of life. Pet owners can identify pannus by looking at the pinkish-white film around the lower edge of the dog’s eyes.
There is currently no cure for pannus and veterinarians are not sure what causes it. But what is certain is that UV light can accelerate the development of the disease. Treatment usually includes topical and injectable anti-inflammatory drugs, such as corticosteroids. Veterinarians also recommend reducing direct sun exposure, for which protective eyewear can play an important role, especially for dogs that are active or those who live in full sun or at high altitudes.
German Shepherds and Greyhounds are the breeds most likely to suffer from shade.
Stopping the development of eye conditions like shading is just one reason why you need to wear goggles. For brachycephalic breeds, such as pugs and Boston terriers, their protruding eyeballs
often carry a higher risk of injury. Dr. Brady Beal, lecturer in veterinary ophthalmology, noted that breeds like this are “more susceptible to abrasions, ulcers and cuts” than long-faced dogs. Sunglasses or goggles can be effective in relieving symptoms in dogs with eye discomfort or previous injuries. A more common choice is an Elizabethan collar, but some veterinarians may recommend goggles for dogs after eye surgery.
