Like people, our canine companions can lose their vision and struggle with blindness, making it important to know the early signs of visual impairment in dogs. Today our network vets explain what you should do if you suspect your dog may be losing their sight.
Your Dog's Vision
Dogs are wonderful, loving animals, and for many of us, our dogs play a significant role in our day-to-day lives.
Your pup's eyes give clues to vital information about the state of their overall physical health. Serious conditions such as liver disease, diabetes, anemia, poisoning, head trauma, pain, auto-immune diseases, and cancer can all present indicators in the health of your dog's eyes. By spotting the symptoms of eye conditions early, your vet may be able to help your dog's eyes feel more comfortable, and possibly preserve or restore your dog's vision.
Signs of Vision Impairment
Whether it's due to aging or other health conditions, below are some of the most common signs and symptoms that could suggest your dog may be losing their vision:
- Cloudy appearance of the eye
- Your dog is bumping into objects
- Signs of anxiety or hesitation when in new places
- Your dog is suddenly unwilling to go up or downstairs or jump onto furniture they normally do
- Eyes are red, puffy, or swollen
- Obvious eye irritation or pawing at the face
- If your dog seems confused, dazed, easily startled
Causes
Visual impairments and blindness can occur in dogs due to aging, disease, injury, and hereditary conditions. In fact, your dog's natural aging process can sometimes include vision loss, ranging from minor issues to complete blindness. That said, it's important for pet parents to understand that blindness itself isn't always the primary issue, but rather a symptom of an underlying condition, such as heart disease, kidney or liver disorders, or systemic diseases.
Common Dog Vision Problems & Health Concerns
Diabetes in Dogs
- Our vets are seeing an increasing number of dogs suffering from diabetes. Dogs at a higher risk of becoming diabetic include older large breeds, breeding females, dogs that have poor nutrition, and obese dogs. 75% of dogs with diabetes are likely to develop cataracts which can result in full or partial blindness.
Dog Cataracts
- Cataracts are easily spotted by pet parents. If your dog has progressed cataracts, you may notice a cloudy appearance in your dog's eye. This condition stops light from fully reaching the retina and can lead to total blindness in dogs. In some cases, cataracts can be operated on which may prevent blindness, but early intervention is essential.
Dog Glaucoma
- Glaucoma is a painful eye condition that feels similar to a migraine headache. While there are treatments available for glaucoma, the outcomes are best if the condition is diagnosed in its earliest stages. If your dog has yellow or green discharge from their eyes, dilated pupils, bloodshot eyes, or is slow to react to bright light, visit your vet as soon as possible. Left untreated this painful condition can lead to partial or complete blindness.
Sudden Acquired Retinal Degeneration Syndrome in Dogs
- Sudden Acquired Retinal Degeneration Syndrome (SARDS) causes a deterioration of the retina, which leads to blindness in both of a dog's eyes. This syndrome develops very quickly in dogs and can result in total blindness in just a few days or weeks. Due to the sudden nature of this condition, dogs with SARDS can have a very difficult time adjusting to their visual impairment.
Progressive Retinal Atrophy
- Progressive Retinal Atrophy (PRA), is a painless condition that results in the deterioration of the retina, potentially leading to blindness in both of the dog's eyes. PRA is an inherited condition that develops at a slower rate than SARDS, which can give your dog time to adjust to their vision loss.
Treatment of Vision Problems in Dogs
The conditions that result in vision loss for dogs typically don't clear up on their own. Early intervention is essential when it comes to helping your dog cope with their loss of sight, or to treat the condition and perhaps preserving your dog's eyesight.
In some cases, conditions that can lead to blindness may trigger other health issues, or your dog's blindness could turn out to be a symptom of a larger medical concern. Making an appointment with your vet for a full examination is the best way to prevent further complications, and possibly save your dog's sight.
