I have a 7 month old male Mastiff named Eddie. I would like find other dogs to go to the park or go on walks with. Eddie is very well socialized with people, however due to winter and lack of friends with dogs, his exposure with other dogs is lacking. Trips to the Petsmart just aren't cutting it. He is about 100 pounds right now (and getting bigger by the day), so the larger the breed the better.
