Here's why:
* Navigation: Dogs rely heavily on sight for navigation. A blind dog would have a very difficult time understanding where they are going and could easily get lost.
* Obstacles: A blind dog wouldn't be able to see obstacles like trees, rocks, or steep drops, which could lead to injury.
* Safety: Being alone in a forest is dangerous for any animal, especially a blind one. They wouldn't be able to defend themselves from predators or find their way back.
It's important to remember: Blind dogs need special care and attention. They should always be kept on a leash or in a safe, enclosed area when outside.
