Brought new dogs into the house but he is just weary of new people dogs and kids. The black dog is really really good with everything. If you decide to go with a lab and happen to find a borador like I have, give it some thought.

The black dog was described almost perfectly in this, other than possible aggression to new dogs.

I have a feeling you may end up with the mastiff lol. It is the only one you keep mentioning. In the end you are the only one who truly knows what you want. Best of luck to you with whatever you decide to go with.
