Here's why:
* Age-related vision loss can vary: Some dogs experience mild changes in their vision, while others might develop more severe conditions like cataracts or glaucoma.
* Not all vision loss is permanent: While some conditions can lead to permanent blindness, others, like cataracts, might be treatable with surgery.
* Other factors contribute: A dog's breed, overall health, and genetics can also influence the likelihood and severity of vision loss.
If you notice any changes in your dog's behavior that might indicate vision problems, it's crucial to consult your veterinarian. They can assess your dog's vision and recommend any necessary treatments or adjustments to their environment.
