A cataract is a clouding of a dog’s eye that can significantly impair its vision, depending on the severity. Any dog can develop cataracts, which may cause pain, blindness or related inflammatory eye conditions, all of which can impact the dog’s quality of life. <\/span>Luckily, early detection can prevent cataracts from progressing and keep your dog happy and healthy as it ages. Here’s what you should know about cataracts in dogs.<\/span><\/p>\n

What Are Dog Cataracts?<\/b><\/h2>\n

Cataracts are an increase in the opacity of an eye’s lens. Healthy lenses are completely transparent, letting light filter through to the retina and resulting in clear vision. When cataracts form, the lens becomes cloudy, and light can no longer pass through. This decreases a dog’s range of vision and, over time, can cause blindness.<\/span><\/p>\n

Untreated cataracts can cause secondary issues to develop within the eye, such as chronic inflammation, glaucoma, retinal detachment, lens-induced uveitis or lens detachment. Because these secondary issues can be painful and irreversible, early detection is crucial in preserving a dog’s quality of life after cataracts.<\/span><\/p>\n

Dog cataracts often appear as a visible whiteness or cloudiness of the eye. At certain angles, they may even appear sparkly or crystal-like. However, you might not notice cataracts when they’re small or just-formed, meaning it’s important not to rely solely on what you see to diagnose cataracts.<\/span><\/p>\n

Causes of Cataracts in Dogs<\/b><\/h2>\n

Any dog can develop cataracts, regardless of its age, sex or breed. However, there are a few known causes to be aware of that might make some dogs more susceptible to the condition.<\/span><\/p>\n

Genetic Factors<\/b><\/h3>\n

Hereditary cataracts are thought to be the most common cause of the condition in dogs. Certain dog breeds tend to be genetically predisposed to cataracts, including poodles, Labrador retrievers, American cocker spaniels, French bulldogs and Boston terriers.<\/span><\/p>\n

Health Conditions Linked to Cataracts<\/b><\/h3>\n

It’s possible for cataracts to form as a complication of other diseases, most commonly diabetes mellitus. Nutritional deficiencies and low blood calcium levels (known as hypocalcemia) are also thought to produce cataracts in dogs.<\/span><\/p>\n

Age and Environmental Factors<\/b><\/h3>\n

While young dogs can develop cataracts, they grow more common with old age, particularly in dogs over 8 years old. Environmental triggers, such as excessive exposure to UV light or toxic substances, are also possible.<\/span><\/p>\n

Signs and Symptoms of Canine Cataracts<\/b><\/h2>\n

Detecting cataracts early can help you preserve your dog’s vision and prevent secondary conditions from forming. Be on the lookout for the following signs of cataracts in dogs.<\/span><\/p>\n
