Kellar the dog was born blind four years ago but owners Marcy Stapley and her fiance Mike Miller have a developed a way for the springer spaniel to play fetch.
The couple from Petersburg, Ontario said despite Kellar's blindness, it did not dissuade his basic doggy instincts to play.
"He was really interested in playing. He tried to chase things at the dog park, but he couldn't find them," Stapely told New York Daily News.
In the video Kellar can be seen using voice commands and his sense of smell to fetch a rubber duck in the park.
Through a period of trial and error, they can command Kellar to play fetch by saying the word "listen" before throwing an item and then saying "hot" in a high excited voice if he gets close to the object, and "cold" in a quieter voice when he is too far away.
