This probably sounds stupid to some of you guys but I need help with my dog he keeps running off. He is a 8 month old Australian sheopard. he is tied up probably 3-4 hours a day in the morning and then I am home I un hook him and as long as I am playing with him or spending time with him he's fine but If I don't watch him for 20 minutes or more he's runs off. I have tried everything, spanking, scolding, kennel time and even a push button shock collar. Just today he ran to my folks house through the woods wich is about 3/4 of a mile away. I don't know what to do I can't have him running.
