I've read all of the posts in this thread and am amazed that no one suggested a springer spaniel. Perhaps I have a bias because we are enjoying our second springer. We just adopted her in June, she is about two years old, weighs about 40 pounds, exceptionally affectionate, loves being in the car, enjoys the outdoors and is great with kids (we have ten grandkids). Activitywise, she is very adaptable. We are an older couple and can't give her the activity level we would like and she seems to be okay with that. When we visit our daughter, who has two high energy springers of her own, our springer keeps up with them. We try to get in as many play dates as possible. My experience with springers is they love people, are not aggressive with people or other dogs, and our current springer is very intelligent. Take a look at
www.springerrescue.org and good luck in your search. But what ever you do, please rescue a dog. There are so many dogs without a good home.
