She rode hard. Lera had a purpose for her haste and the animal between her legs could sense it. It could also sense her rage, her anger, and that made it fear the sword across her back even more. I am no coward, she thought. I could have fought the Raiders! I have twice the ability of any boy and three times the skill! She swallowed back the tears that threatened to overwhelm her. It wasn’t just her disappointment that upset her. It was that her mentor, her father, had thought her incapable of handling a real battle. Instead, she was forced to carry a warning of the impending danger to other villages like the isolated one she called home. The only other thing she could do was hope that those she loved had survived.

Tell me what you think ~Fetch
 

Kind of the same deal with the animal. If the animal is a horse, then tell us so. If it is some alien creature that only exists in your world, then tell us what it is and then give us some description. I was left wondering what kind of animal it was, and by the time I noticed I was no longer paying attention to the story, I was done reading it.

You also have a POV break when you tell us that the horse is feeling Lera's rage, and then in the next sentence we hear Lera's thoughts.

It looks like you have a start of a good story idea here.
