Short answer: The only proven cure for cataracts in dogs is surgery to remove the cloudy lens, usually replacing it with an artificial one. It has an 80–90% success rate in good candidates. There are no eye drops or diets that reverse a cataract — medication and antioxidants can only slow progression or keep your dog comfortable. If you notice cloudiness in your dog's eye, see a veterinarian (ideally a veterinary ophthalmologist) early, because timing affects how well surgery works.
What are cataracts in dogs?
A cataract is a clouding of the lens inside the eye. The lens should be clear so light can focus on the retina; when it turns cloudy, vision blurs and, left untreated, can progress to blindness. Cataracts are commonly linked to aging, but they can also come from genetics, diabetes, eye injury, or inflammation. In diabetic dogs especially, cataracts can form quickly — sometimes within weeks — so any new cloudiness deserves a prompt vet visit.
What are the early signs?
The signs are easy to miss at first. Watch for a cloudy or bluish-gray look in the pupil, bumping into furniture or walls, hesitation before jumping or using stairs, general clumsiness, or increased clinginess in unfamiliar places. A quick note: as dogs age, many develop a normal hazy blue tint called nuclear sclerosis that does not harm vision. Only a vet can tell the difference, which is why an exam matters.
How do you treat cataracts in dogs?
Treatment depends on the severity and cause, but the options come down to four:
- Surgical removal (the only cure). A veterinary ophthalmologist removes the cloudy lens with a procedure called phacoemulsification and typically implants an artificial lens. According to the American Kennel Club, surgery is the definitive treatment and most dogs regain functional vision. Success rates run about 90% at one year and around 80% at two years for good candidates.
- Managing the underlying cause. If your dog is diabetic, getting blood sugar under control is essential — it won't clear an existing cataract, but it protects the second eye and reduces complications. VCA Animal Hospitals notes that anti-inflammatory eye drops are often prescribed to control inflammation the cataract itself can trigger.
- Diet and antioxidants. Antioxidants such as vitamins C and E and carotenoids may help slow progression in some dogs, but they are not a cure. Only use supplements under your vet's guidance.
- Regular monitoring. If surgery isn't chosen, routine rechecks let your vet catch complications like glaucoma or retinal issues early and keep your dog comfortable.
Is cataract surgery worth it, and what does it cost?
For most healthy dogs, surgery restores a good quality of life. In the U.S., cataract surgery commonly runs roughly $3,000–$5,000 per eye, which usually covers the pre-surgery testing, anesthesia, the procedure, and follow-up care. Your vet will run tests (like an electroretinogram and ocular ultrasound) first to confirm the retina is healthy and your dog is a good candidate. Talk through the risks — dry eye, glaucoma, and retinal detachment are the main ones — with a veterinary ophthalmologist before deciding.
Can you prevent cataracts in dogs?
You can't prevent age- or genetics-related cataracts, but you can lower risk and catch problems early: manage diabetes carefully, protect your dog's eyes from injury, and get regular wellness exams. Feeding a healthy diet supports overall wellbeing, which is where we come in on the treat side.
Helping a dog with vision loss stay happy
Whether your dog has surgery or you're managing cataracts long-term, keeping their mind engaged matters as much as their eyes. Dogs rely heavily on scent and taste, so lean into that. Keep furniture in the same spots, use scent-based games, and reach for long-lasting chews your dog can enjoy by nose and mouth rather than sight.
At Bully Sticks Central, our chews are 100% natural, single-ingredient, 100% real meat, fully digestible, and contain no rawhide — ethically sourced from grass-fed American and Argentinean farms. A simple, mentally engaging chew is a great way to keep a vision-impaired dog calm and occupied. Our single-ingredient chews guide walks through the safest options, our classic bully sticks are a favorite for slow, satisfying chewing, and if you want an easily digestible pick for an older dog, see our take on safe trachea chews.
The bottom line
Cataracts can feel scary, but you have real options. Surgery is the only cure and works well for most dogs; managing diabetes, using prescribed eye drops, and regular vet checks keep your dog comfortable when surgery isn't the path. Either way, early diagnosis is your biggest advantage — if you see cloudiness or your dog is bumping into things, book a vet visit. You're your dog's best advocate, and a little vigilance goes a long way. — Preston Smith, co-founder, Bully Sticks Central
