Help! We need advice! What kind of dog shall we get?

Is this our perfect match?

I soooo want a dog. We haven't had one for years. Not because we don't love them; but because we want to be the right kind of dog/parents. I think I'm ready to take the plunge. But the question is; just what kind of dog will fit into our family? We are empty nesters with grandkids that visit us; so our canine friend must be kind and patient. We don't care for high energy jumpers and yappers; but we are walkers and can commit to daily walks. We have a big yard but may eventually buy a smaller place; but will likely always have some kind of yard. My hubby works full time and I work 6 1/2 hours per day during the school season with summers off. So we need a pet that can handle some alone time. I want a dog with a gentle face; like a golden retriever or spaniel has. Nice eyes are important. What do you think? What type of dog would work in our household? Send me your comments, I'd love to hear. Right now; Field Spaniels top my list; but I'm worried about leaving them alone. Thanks for your help!
