OK I know I watched this movie when I was like 8 or something but it had a flying dog that was white and his name was sebastian and that's all I can remember someone help me

Could it have been "The Neverending Story"? The dog's name wasn't Seabastion, though, the boy's name was. Don't rmember the dog's name

The dog was actually a dragon named Falkor.

It was definitely the Neverending Story, and the name of the luck dragon was Falkor. Bastian was the name of the boy in the movie, not Sebastian.
This is my ALL-TIME favorite movie... I have it all memorized! :)

Neverending Story... ahh those were they days!

Whenever someone needs help with this movie, they always turn to me because I know like everything there is to know about it! It doesn't get much better than this movie... it's such an unforgettable film, and it's so much fun to watch no matter how old you are!

Parts 2 and 3 were OK also but the first is the best.

I have to 100 percent agree with you that the first one is the best! I saw the second one in theatres, right in the front row no less, and loved it. The third one was a complete waste of time in my opinion... it didn't have the same feel as the first two.
Anyway, if anyone ever needs info about this movie, or if you have a question about the first one, let me know because I'm totally the right girl for the job! :p

Yea that is an all time classic movie, and I agree the 1st one was the best.

OOOOOOOOORRRRRRRRR

IF it's a cartoon, is Belle and Sebastian
