don't have a favorite bread (each one has it's own traits) and every dog i have had i've loved them all (the list of dogs i've grown up with)
australian sheep dog
2 mutts (one was a Shepard mix other was a spring mix)
Bernese mountain dogs (she was a big dope and we loved her lived to 10)
Shiloh Shepherd (she's the big one in my avatar)
Borgie (border collie and corgie mix, she hyperactive to all hell and a bit neurotic)
that being said i send to like bigger dogs (hell my shiloh is 100lb and small for her breed) most of the smaller toy dogs i find to be yappy and a bit mean.
I have a mini poodle and a shih tzu right now. They are great dogs but a Standard poodle is one of the smartest dogs you can imagine and a golden retriever is the best all around dog. They are great with kids, easy to train and pleasing their person is the most important thing in their world.
I don't know if I have a favorite but I've always wanted a Dogue de Bordeaux and an Olde English Bulldog. But mutts are great too. Currently I own one and she's the best little dog.
