Are there any animes like Inuyasha which has dog demons or dogs which are the main characters? please Im desperate!!

Sadly no, there is no other show like InuYasha. Even though there should be more.

I know there is Kekkiashi~ although it is the main characters companions that are the dog spirits. They do not change into human form (they can talk).

There are more anime's about wolves... but keep looking. Good Luck.

I know the manga Koyoi kimi no chigiri,if it helps... :S <:)
