At age of 1 jermg had so much energy we would play fetch for 1.5 - 2 hours non stop to tire him out or a good two hour hike/ water fetch... But hes still a pup and will become over excited at times just make sure your reaction is calm to not fuel his excitement... By 1.5-2 years he calmed down a lot
I would recommend not just physical but also mental exercise
