Some seeing eye dogs are selected from breeders specifically because they possess a certain temperament that is required of service dogs.

If the dog passes the tests, they are then taken to a training facility.
That being said, eye drops for dogs are nearly identical to those used for humans. Most eye drops are simply a saline solution, which is a small amount of salt dissolved in water. This is a great reproduction of human tears, and dog tears are composed of nearly the same elements. When you're considering using eye drops to treat an Eye Infection though, always get an opinion from your vet.
