well, the best anime ever with dog ears IS inuyasha (as you mentioned ^^ lol!!)

gilgamesh is not really a romance series... there is love in it though... and wow... i think youll cry! i really cried at the last ep!

um... ive never seen the series Bokura ga ita (romance) but people always reccomend it to me and tell me it has a really sad ending ( i dont usually watch romance anime much ^^)

hana kimi is a really great series (manga/drama) also called hanazakari to kimitachi e.
the end isnt really sad... well... i cried... but thats because it was one of my longt time fave mangas and it ended. also cuz something sad happens... but its not like "omg cry" type sad.

bitter virgin is sad. its a manga... you can read it at onemamga... but its sad. though it hasnt ended yet... its still sad... ^^

okane ga nai is my fave yaoi anime (well, right after gravitation ^^) theres only three OVA's out now... but the manga has already reached chapter 23 ^^

you should also watch the firs OVA of close the last door by yuugu yamada. its really awesome. the also have the manga at places like mangatraders and youtube.

and you might want to try the series La corda d'oro. some eps are kinda sad... and theres no REAL romance (there is some though ^^)... but its a very...er... "musical" show and its just way awesome!!!

hope this helps ^^
