I am a huge fan of all the molossoid type dogs. I prefer the big guardians, mastiffs and dogs that work for a living or simply because they like it. I respect people who keep these top tier dogs of dogdom and know the amount of work it takes to keep them and to protect them from crazies.
Since 1996 I started a few dog groups and online albums that were very popular in the pre-Facebook era. My flagship site https://molosserdogs.com is still online and running but like most independent sites including Chaz traffic and participation are low. I have a feeling that the individual sites will gain favor again as niche networks become more full featured and popular.
