There was a problem hiding this comment.
Note: in reality, we may want to filter before we map to avoid doing extra work on the emissions we'll eventually ignore. But since the desired output adds the source stream's emission number to the string, we have to filter after we map.
For example, if we filtered first and then mapped, then the output would be Dog #1, Dog #2, etc. If we map and then filter, the output is Dog #1, Dog #3, etc.
If this doesn't make sense, try switching the order and you can see it in action :)
