A question about the ellipsis

[PJMcK]

When using an ellipsis to indicate a cut or pause in text, how does one type the second set? Do the next words come right next to the three dots or should there be a space?

For example:

"As the man walked... he looked for his dog."

==OR==

"As the man walked...he looked for his dog."

Should the ellipsis come at the end of a line break, how does one handle the ellipsis?

"As the man walked...
... he looked for his dog."

==OR==

"As the man walked...
...he looked for his dog."

It's a little thing but I couldn't find the proper rule.

Thank you, in advance.
