A talk about pets

Today I was remembering my pet. I had a Labrador Retriever dog, he was golden, and I used to walk with him and run too. He was more than an animal, he was a friend. Everytime that I watch the movie "Marley and Me" I remember him, to the reason which is why I have wrote written this note. Regards (in english, we do not use "regards" often) be careful (with?) your pets.

Very good english, good job!
