Mmmh, but in German you can say "Der Hund sprang auf den Tisch und biss ihn". This kind of ambiguity can be a lot of fun. (It can also be confusing, I admit. But it can be fun, too.)

EDIT: Well, in English you can say "The dog jumped on the table and bit him", but it is not ambiguous. ;-/ The ambiguity in German is not due to gendered pronouns, but due to the gender of table/Tisch. :-|
