It is hard to know, when adopting apuppy, what you are getting. If you if adopt a purebred, it may have the exact temperment of the breed, but it may not.

In general, many people say adding a dog of the opposite sex is the safer bet. We had one female, who was 13 months old, when we got out second, dog, anther female. They were and are the best of friends. A few years later, we added a 2 1/2 year old male, and they are all the best of friends. My sister has 3 females, and they get along great as well.

It is really hard to make generalizations about what will and won't work. It sounds like an active dog, would fit in with your family. If you feel good about it, go for it!
