There are still lots of things we need to know before we can make an accurate guess as to what would be good for you..

*Do you want a dog that will be a good watch dog or guard dog?
*A dog that you can do agility, flyball, etc with?
*Does it matter if the dog sheds alot?
*Do you want a breed known for it's obedience? Or would it matter if the breed is known to be quite stubborn?
*Do you want a breed that is known to be quiet?
*How much exersise are you willing to provide? Do you want a dog that you have to take for an hour long run everyday, or something that only needs a 20 min walk around the block? Couch potato?
