It's raining

* "Me and my dog" would be heard everywhere in this usage (as a subject), but is bad grammar. In English, people often listen to the people around them and choose grammar to fit in with them, so you might want to do that. But in any formal context, social or in writing, you would probably do better to stick the correct "my wife and I", "my friends and I", or even "I and anyone who wants to will go to ..."  

Of course, as the object in a sentence, "me and my dog" would be completely correct - so, "the guys at the station were very kind to my dog and me (or even "me and my dog"), and let us on to the platform."

It's raining

Ciao, Paulo - Prova questa correzione:

After a long dry period (or "spell"), today it is finally raining.  Anyone with a garden will be happy, but my dog Blue and I ("I" always comes last, just the opposite in Italian) will not be so happy (or "will be a little less happy").  When it rains, you can't run around in the meadows and play with frisbees. 

Un buon sforzo, Paulo!  Spero ti aiuta. 

Saluti,
