I am so sorry you lost your pal and the best friend. I know how hard it is to lose a pet as they become such a BIG part of the family. We had Great Danes and I dearly loved them. The first one did everything but talk, had a great sense of humor and was so smart, gentle and kind. It took 3 to fill up the hole he left but then each of them had their own personality.
BTW, I just finished reading Sophie which is the story of the Blue that fell off a boat in New Zealand, swam in shark infested water to an island and lived on her own for 6 mos. before she was trapped and by odd coincidence "found" by her family who adored her. If you do a search for "sophie dog overboard" you can read about her.
Another dog here in NM named Blue who was in the news here. He belongs to the town and no one owns him. He hangs around one of the local stores and the storeowner makes sure he's fed. He made the news because a couple people insisted that he needed to be on a leash BUT no one owns him and he's caused now harm. As a matter of fact, he's got his own Facebook account and is loved by the majority of the townspeople.
Another dog you should Google is the Great Dane named Giant George. He has his own web site, has flown to NY, been on Oprah and Today and is the tallest dog.
