Ridiculius
Ridiculous is spelled incorrectly.
As he began to walk toward a clearing he heard something.
You're missing a comma, which should be between 'clearing' and 'he'.
He lost his footing and quickly feel down onto the earth.
You mean 'fell' here.
"Come here boy. Its ok." He talked in a soothing voice to cool Growlithe's nerves.
As I've said many, many times before, you should make the H in He lowercase. Why? Because the sentence is still going on, despite the dialogue being over.
As he started to walk away the Growlithe ran to catch up. "No go back." he tried to keep it from following him as he pushed it back every couple steps.
Whenever you start a dialogue/monologue/any-kind-of-logue, you should start a new paragraph. It's easier to read.
All right, everything else seems to be good, though this part of the story seemed rather. . Bland. Like there was no emotion to it. We don't even know what the character looks like at all, but I'm sure we'll find out. You have a fair amount of description, though more wouldn't hurt. Like saying "The rain had just began and woke him up." won't cut it. Instead, say where the rain had fallen. His face? His hands? His legs? Was it a heavy rain or a drizzle of rain? What was he thinking at the time? Was he in any pain? Or was he just lying on the ground?
So, I suggest to state these kinds of things when writing. I'll be back for another review! ^_~
Hope this review helped! ^^
