My mother grew up with Boxers... and from what she has told me, they are one of the best dogs you can find. They're loyal, funny and most have a great personality. Don't get a common dog like a retriever or a Lab, be unique.. you don't see many Boxers out there. You can't go wrong with Boxers, but they don't like cold environments... so think of that before getting one.

P.S.

BEFORE your thread is hijacked and made into a "which dog is good" thread.. the answer to your question is yes they are good dogs and yes they are easily trained. The were used as police dogs in the past.
