SQL & PL/SQL :: Query Using DBLink Returns More Rows Than Direct Query?

I have a query that is pulling back more rows when I use the dblink than when I hit the linked database directly.

For example:

select
x,y,z
from
mytable@dblink

returns 788,324 rows

while
select
x,y,z
from
mytable

returns 712,102 rows

It's the exact same query, with the only difference being the dblink. It's not pulling the data into a cursor or array, it's a simple, straightforward query on a remote database.
