That was really touching.
I did like the description as well, of the dog and the things that they did together.
Also liked the observation about him being real becasue he was always there.

I thought this was really sweet. I thought that you did a really nice job with characterization. I thought that it was commedable that even though you didn't explicitly say that her friend was a dog, you were still able to say that he was.

Grammatically you were fine mostly. In this sentence, "And because you were always by my side, because we were always together, I wasn’t lonely anymore," I think you could change the second "because" to "and." I'm not sure if you could use the word twice. As far as the dashes, I think they're ok but I don't think they were necessary.

Hmm... The story reminded me of Blacky, inevitably. Thankfully, she will always be somewhat immortal to me. She came as my guardian spirit, she will leave as a spirit XD.

Erm, I don't think you really want a critique, do you? This reads most like a reflection/memory/ode, however you'd like to call it. There aren't any errors I can see that scream out blatantly.

I'm not constructive today. I hope you will forgive me XD. I don't thin kit is fair to review something without looking back at it and analysing it... err. why am I reviewing this now, then?

*runs away, but runs back*

I do compeltely agree with you. "Feeling something is better than feeling nothing." :3

Thanks for it, anyway. It reminded me of the better of my childhood spent wandering around waif-like with scary black-cat guardian Blacky...

Your story really touched me and I really like ur writing style. couple of minor spelling and so, but overall, it is beautiful.

oh, sorry about ur first friend.
