A golden retriever's permanent look of positivity has inspired others to overcome obstacles.
Appropriately named Smiley, the dog, who has dwarfism, was born without eyes, leaving the appearance of a big smile across his face.
Ontario dog trainer Joanne George rescued Smiley from a puppy mill when the dog was about 1 or 2 years old. Smiley was able to adapt to George's household and two other dogs despite his disabilities, George writes on her training website.
George also notes on the site that Smiley ended up changing the way that she approached training other pups. She says that her program, Training the K9 Way, aims to teach dogs self-control and willpower, areas in which Smiley has easily succeeded.
"He is certainly inspirational to everyone he meets," George states on her site.
And it's that inspiration that led to Smiley becoming a therapy dog.
"I realized this dog has to be a therapy dog -- I have to share him," George told CBS News.
A decade after being rescued from the puppy mill, the certified therapy dog spends his days visiting retirement and nursing homes. According to CBS, Smiley also attends a library reading program for children with special needs in Stouffville, Canada.
Smiley is also the face behind George's training business, helping others smile along with his success.
