Signs Your Dog Is Going Blind
Sometimes it’s obvious when a dog is having vision problems. He may bump into walls and other objects, act fearful or have trouble finding his toys and food bowls. Other common signs are blinking and rubbing eyes with paws.
However, many dogs don’t show obvious signs of vision loss, especially when the onset of blindness is gradual.
Subtle clues that your four-legged pal’s vision is failing include:
You can also check your dog’s eyes for physical signs like blue-tinted or cloudy eyeballs and enlarged pupils.
Schedule a veterinary exam immediately if you’re worried that your dog is going blind. A veterinarian will perform several exams and tests to determine the extent of your dog’s blindness, diagnose the cause, and develop a treatment plan. The exam may include an assessment of the dog’s cranial nerves, neurological exams, imaging and bloodtests.
Some dog breeds, including dalmatians, German shepherds, chow chows, bassett hounds, chihuahuas, are prone to losing their eyesight. Blindness in these breeds is often due to defects introduced through breeding.
Old age is another common cause of blindness in dogs as their eyes simply wear out over time.
Dogs can also go blind after losing one or both eyes to injury or cancer, and some go blind due to other illnesses. The most common illnesses that can take your dog’s vision are:
Whether a dog’s loss of vision can be successfully treated or not depends on the cause and the extent of the damage. Vision can often be improved in diabetic dogs by administering insulin and keeping blood glucose levels even.
Cataracts can be removed and restore partial or full vision. However, surgery is required for this process. That comes with its own risks, of course. And, anytime a dog has to undergo a procedure with anesthesia, there are inherent risks with that as well. It’s also important to prepare yourself for the postoperative care as well as to make sure your pet is fully prepared and healthy for the surgical and healing process.
Medications can treat glaucoma but often cease to work, with the result being the affected eye must be removed. Breed-specific blindness can sometimes be treated depending on the underlying issue. There is no effective treatment for blindness caused by aging or SARDS.
Corneal Ulcers:
A corneal ulcer is a wound on the corneal surface. When a dog has a corneal ulcer, fluid will accumulate in the stroma, which makes their eye appear cloudy. A corneal ulcer is very painful for a dog, which may cause your dog to rub their affected eye to relieve some of the pain. They may also tend to keep their affected eye closed in an attempt to protect it. The most common cause of a corneal ulcer is trauma to the eye. Bacterial infections, viral infections, or other diseases are less common, but still possible, causes. Surgery may be required to protect the injury in the eye and promote healing.
Glaucoma:
Glaucoma is a buildup of fluid inside the eye and can be quite painful for your pup. Glaucoma can cause the retina to become damaged, which can result in blindness. Symptoms of glaucoma are typically noticeable and progress slowly, so it’s easy to spot the disease in its early stages. Symptoms of glaucoma include yellow or green eye discharge, dilated pupils, a blue tinged color to the eye, and bloodshot eyes. You can easily treat glaucoma with medication eye drops if it’s caught early enough. But if the disease continues untreated for a long period of time, it can lead to partial or complete blindness.
Causes of Sudden Blindness in Dogs (+ how to help them cope!) – Dog Health Vet Advice
Three years ago, my now 17-year-old retired service dog Mercury started going blind. Even though I had worked with dogs for 20 years before he started losing his vision, I didn’t know much about blind dogs. Naively, I thought his blindness would dramatically change his life.
It turns out, I had a much harder time than he did adjusting to his blindness. Initially, it was hard for me to realize that this dog who had saved my life wasn’t able to see me anymore. But, once I stopped feeling sorry for him (and myself), I was able to recognize that he wasn’t struggling or afraid. Watching my blind dog continue to love life, train, earn trick titles, hike, and surf—all while not being able to see—has inspired me to teach others not to shortchange blind dogs of any age.
Canine blindness and loss of vision can be caused by a variety of conditions. Sometimes blindness is a natural result of conditions associated with old age. For other dogs, it comes on quickly when they are quite young. Common blindness-causing conditions include cataracts and glaucoma, as well as Sudden Acquired Retinal Degeneration Syndrome, or SARDS. As the name implies, dogs with SARDS lose their vision quickly instead of it slowly deteriorating over time.
If your dog begins bumping into things or seems disoriented and you suspect they’re losing vision, make an appointment with your veterinarian right away. In addition to diagnosing your dog’s vision issues, the vet may refer you to a canine ophthalmology specialist.
For dogs who have lost their sight, maintaining routines as much as possible can help them adjust. Keep your furniture in the same spots to make it easier for your dog to navigate your home. If you redecorate, or when you bring your dog to a new place, bring them carefully around the area to show them obstructions. Because your dog can’t see, make sure that any potential dangers such as swimming pools or staircases are blocked off with fences or baby gates to prevent falls.
If you find your dog bumping into things frequently, talk with your vet or canine ophthalmology specialist. They may recommend a bumper like Muffin’s Halo that can help protect your dog’s face.
Many blind dogs are able to happily return to activities they enjoyed before losing vision. So, where possible, don’t stop engaging in activities that your dog has always loved. However, make sure to always keep blind dogs on leash so you can prevent them from walking into things or getting hurt.
It’s also essential to inform people who interact with your dog—such as groomers and dog walkers—about your dog’s condition. Most people who see my dog Mercury have no idea that he’s blind, but I still like to advise anyone who approaches us so that they don’t startle him. You can also purchase leash and collar wraps that say “blind dog” to communicate to others that your dog is visually impaired.
Just because a dog can’t see doesn’t mean they don’t want to play! Play is an important part of life for dogs and loss of sight doesn’t mean that playing days are done. When playing, blind dogs utilize their other senses to compensate for a lack of sight. So, opt for toys that squeak, rattle, and make noise when they move, so that your dog will be able to find them.
Even for experienced owners, it can be shocking to see how well most dogs adjust to going blind. Blindness need not create a change in your training routines with your dog. It just may require some shifts in how you cue certain behaviors. Obviously, your blind dog will not be able to respond to visual signals. However, verbal cues work well to help blind dogs maintain existing skills and learn new ones.
Luring with treats and then incorporating physical cues can work well with blind dogs. For example, a shoulder touch to cue a sit or a back touch to cue a down. Keeping blind dogs physically and mentally exercised is important. Training continues to build self-confidence as well, which is particularly important for dogs with impaired vision.
While discovering that your dog has become blind might be overwhelming or even devastating for owners at first, it’s important to recognize that blindness isn’t a death sentence. Dogs who go blind can and do continue to go on to live enriched lives. They just need a little extra help from us to keep them safe. https://www.akc.org/wp-admin/admin-ajax.php Get Your Free AKC eBook
