As children, my brother and I watched this film on television and we both enjoyed it. The story really tugged at our hearts because it was funny and sad at the same time. We both talked about this film for days after watching it.
I liked "Dondi" because I liked the handsome lead actor, David Janssen, who was then at the height of his popularity for starring in the television show "The Fugitive". The lead actress was Patti Page, who happened to look like my mother, so I liked watching her.
The film also included character actor, Robert Strauss. I had never liked him because he always played tough characters. However, in "Dondi" he played a tough guy with a soft heart and won me over. He played well against goofy Arnold Stang's character. Strauss and Stang were fun to watch together.
If I were to see this film again today, I'm sure my opinion of it would change. It's not one of the better films I saw as a child but it is one of the films I remember with affection.
