depends on how fast and how diversified the running is.How much is "alot" though? 1 hour running, 2 hours running 3,4 etc
I have a Gordon Setter, which is also a gundog and of similar size. She is 18 months old now and I walk her 2.5 hours every day during the week and more (up to 4.5-5 hours) on the weekend. At the same time we started gundog training when she was 5 months old, do obedience training - all for her mental stimulation. She is very calm at home and has never destroyed anythingIt's a short answer but generally sporting breeds like that are high energy and need a lot of exercise. I have heard they need a lot.
