Searching for a memory

I have been looking for a cartoon that I remember seeing when I was very little, I remember it being in a very different style then what I was used too. It was about a boy who somehow got wishes and all I remember is he had 2 or 3 really beautiful horses and a donkey that was special to him... I believe the donkey was named Fitz... Fritz something with an F. In part of the story they capture some really pretty birds and there is really pretty nightscape in a field (not that, that is overly helpful to remember the landscape in a cartoon but I remember it vividly). I've been able to track down most of the cartoons that stuck with me as a kid growing up in a small town I would always dig through cartoon collections in video stores and libraries looking from something different, this is one of the only ones I haven't been able to track down, I still have dreams about it sometimes... I don't think I'm making this up... I'm really not that creative but no one I know remembers it and I wouldn't put it past my brain to be combining two cartoons so if part of this sounds familiar and part doesn't then please suggest anything that resembles this.

THANK YOU!!! so so much this is totally it. Well that makes sense I come from a Russian Ukrainian immigrant community I must have dug it out at the library. I assumed it was some anime or other and for the life of me could not find this again.

Wow re-watching this I now know why I was so captivated despite being so old it really is a beautiful film, and the character dances about in it a lot I probably enjoyed it so much as a kid because well number 1: Pretty Horses number 2: I was in folk dance classes when I was young I recognize some of the dance steps of the character and music in the film. This is so so cool to rediscover and I'm so glad it's as awesome as I remember.
