Interesting. I haven't seen any "overly" hyper actions in probably 5 years. I will say they do tend to get hyper but nothing out of the ordinary for a happy dog. thinking back to his prime, he was quite hyperactive in snow for some reason when my family was outside(shouldnt impact you haha). they are pretty good with knowing what kind of environment they are in. Never had trouble with him being crazy in the house, scratching hardwood floors or making a mess. The hyper a english springer shows is nothing compared to, say, a border collie which is something my parents would of never put up with.
Training was easy. retrieving,sit,stay,high five,paw,... all that jazz.
all in all its a easily manageable friendly dog. Now hes old and slower
