Wow! a Springer Spaniel will be a high activity dog! here's my suggestion; make a list of things you're looking for in a dog- based on your lifestyle. then spend some time researching different breeds, there's a rescue for every breed out there.
For instance I have always had large breeds; shepards, labs, colllies, ect. When my Felicia passed I knew I wanted a large dog, but non agressive, a companion dog that didn't require alot of exercise, as I was horribly fat. Some one to lay on the couch & eat cookies with, no digging no shedding. So I did some research and ended up with a Greyhound. They're medium to large inside dogs, non agressive breed, and mostly only need 20 or 40 mins of exercise a day. they are big couch potatoes. My Male was 85 lbs, and my female is 50. Good luck!
