    A rescue group made sure hunting dogs Herbier and Hilda were adopted as a pair since Hilda helps Herbier get around.

For more than 50 years, guide dogs have been trained to help humans with vision challenges live without boundaries and enjoy independence in their homes, offices, and the community at large. Given dogs' ability to be trained, along with their skills, it seemed unavoidable that there would be an unofficial guide dog for a blind dog.

Almost more exciting is the fact that one such set, which was abandoned together in Salem about a month ago, has found a new forever home that will allow the blind dog and his caretaker dog to remain together.

A little more than a month ago, someone abandoned three dogs over the fence of a local gentleman who formerly rescued greyhounds. The man no longer rescues the little dogs of being long of body, short of leg and droopy of ears, but he did know to take them to the Marion County Dog Services shelter.

The county shelter knew immediately to contact Diane Young at Salem Dogs, a local dog rescue known for being heavy on love and affection that the county most likely has on speed dial.

The rescue director responded in time, taking in the two of the dogs. One black male was healthy and passed tests quickly and easily. He was put up for adoption at the shelter and was quickly accepted.

The other two are between the ages of 4 and 5, required a bit more care. Hilda, a long-haired, black-dappled female, was obviously connected to Herbier, a light-brown, smooth-coated brown greyhound who had vision problems.
