Your opinions on good dog breeds please

I'll second the pitbull for a great companion....I have 2 right now, and they come to work with me every day....1 is 90 lbs, the other is 50 lbs. Great disposition, very loyal, love people, and good security too. Forget the hype in the media, they only show the owners and dogs that flush its reputation down the toilet....not us good owners.
