If they're any thing like my austrailian shepards fatigue isn't a issue. I have to make mine stop and take a drink when were working cows. They'll work day light to dark if you let them. The 10 yr old shepard ive got is retired now but in her prime she'd work a 10-12 hour day then want to fetch when we got home for a hour


I think they are talking about cold water/swimming fatigue


We will burn that bridge when we get there
