Pick a breed you like and is inclined towards the behaviors you desire. Train it and love on it. You will be a bigger factor in the outcome of your dogs behavior then the breed. Puppies are a lot of work, plain and simple. If you have the time and desire to do it right, go for it. But remember, like other members have said, you get out what you put in. Some breeds are naturally very found of humans and other dogs, like the golden doodle. Does this mean that they don't need training? No. But it might make their training easier and quicker. just give it 15 minutes a day, every day. Our dog is a rescue and she is awesome, except when somebody comes the door, she explodes. She gets so excited, and needs to "warn us". We should of nipped that behavior in the bud. Be consistent and I bet that you can fit in the time to do it right. I wish you the best of luck to you and your future pup!
