Did Helen Keller use a guide dog?

According to her great-grandniece, Keller Johnson-Thompson, she had several pet dogs but no guide dog:
"Although Helen had many dogs throughout her lifetime, she never used any of them as dog guides, as many blind people do today. But as she made her way through her gardens later in life, several dogs could always be seen at her side. Some of these dogs included a Great Dane named Belle, a Scottie named Darkie, German Shepherds, Collies, and even a Dachshund named Sunshine."
