I have two favorite breeds, and I currently own one of those.
My two favorite breeds are Golden Retriever and German Shepherd.
We have a 3-year-old Golden right now. He replaced the Golden we had who died in 2008 at the age of 14. They are wonderful dogs: smart, sweet, stuck on happy, and well-behaved. And there isn't a breed that is better with small children.
I have always loved the majestic look of the German Shepherd. We had one briefly in Maine, when we worked with troubled teens, but had to get rid of her because we didn't have the time to give her the training and stimulation she needed. We were, however, very judicious in choosing a new owner. We found a couple (he was a retired NASA engineer) that owned a large farm in SW Maine. The wife was looking for a young German Shepherd to take the place of her 11-year-old German which she took on long walks every day. It was a perfect fit.
Now that I no longer work in the troubled teen field, my next dog will be a German Shepherd.
