Any tips on when, if ever, the exercise needs let up? Copper is around 1.5-2 years old (I'm not sure exactly how old because he's a rescue dog)and mostly catahoula. Right now he goes to a 40 acre dog park every day and needs 3 additional walks. I am exhausted and not looking forward to winter. Will it every let up?
