From what I can remember, most of the chapters (if not all) were drabble style. Kagome is basically this unconventional princess that can't get anything right, including being kidnapped by a large demon dog instead of a dragon. And yes, Sessh is the dog. He's a prince that's cursed to be in this dog form by Kagura.

Other details that I can remember is that Kouga and Inuyasha pop in in earlier chapters as potential suitors but kept being driven away by Sessh, with Kagome helping him by stating she doesn't want to leave her captor's castle. Sango comes in later chapters and you find that she's a good witch.

The last update I recall was that Sessh's spell was broken and Kag and he were preparing for their wedding. I'd be greatly appreciative of anyone who can give my the fif's name!

I'm dead certain it's this:

Fractured Fairytale by R.M. Avalon
Kagome just can't quite get the hang of being a fairytale princess. And it doesn't help that her prince is a total dog. Won 2nd Best Humor and 3rd Best Drabble 1st Quarter 2011.

P.S. The author is no longer active on FF communities due to personal reasons. She has stated that it is highly unlikely for her stories to be completed in the future

That's the one! And yes, I remember her saying that as well. Thank you!

No problem! Glad I was able to help!
