Can I use "catch" instead of "fetch"?
The word "fetch" means for and then bring back, it is used in this video because the stick is first thrown and then the boy expects the dog to go and get it. This is actually a game played with dogs and the game is called "fetch". If we used the word "catch" in this context, it would mean the act of grabbing an object in motion, in this case, the stick. Ex: Can you fetch me that bag? Ex: A. Catch! B. No! Don't throw it.
