Missing near Towner/Upham. REWARD OFFERED.

my white German Shepard, Cain and my black and tan Anatolian Shepard got loose. Athos has a chain collar with a broken cable tie attached to it, Cain does not have a collar. Both are very friendly, however, i have not seen them around strangers away from my house. We found a fox den on the back of our property with dog prints so they may have taken off after a fox. Let me know if you see them please.
