Harvey, who was diagnosed with retinoblastoma just as he turned 4, has written about his buddy dog, Finn.

This is Finn he is 2 years old, he is a labradoodle, I am Harvey and I am 7.
I wanted a guide dog because of my eyes, but we ended up with Finn who is a buddy dog. That is because he doesn’t like to wear a harness.
I like to take Finn to the park, I throw the ball for him and I have to fetch it! We do lot of recall training, where I make him sit and stay, then I walk away and blow my whistle 3 times for him to come.
I really love Finn and we have lots of fun. Here is a video of me and Finn doing our recall training.
