Kellar was born completely blind. But despite being born with no eyesight, it never stops him from having fun. Kellar teaches us that determination is an integral part of life and you can achieve anything with it.
His parents initially taught him how to play fetch using some simple commands like hot and cold. They later added left, right, passed it, and warmer.
The process of teaching and learning took about a week for the basic commands.
Check out Kellar now, though. He is an absolute champion playing fetch just like the other dogs.
