Very descriptive, I like it! But, in the beginning (maybe this is just me being brain dead, but) I thought that summer was the season and was extremely confused! You might want to sort that out, and make sure the reader knows that Summer is a dog. (I thought that it was the season, and that you were overly using personification.)
Follow your passion. Stay true to yourself. Never follow someone else's path unless you're in the woods and you're lost and you see a path. By all means, you should follow that. — Ellen DeGeneres
