She walked the dog with my mom and dad when our dog sees another dog.

He runs after it and my sister holds the leash!

Anyway, the dog pulled the leash so hard that my sister haved to run behind him.

The dog goes so fast she falls and hit her head on the path and cuf both of her lips and her nose.

She's OK now and she still loves the dog! He wasn't sorry at all!
