My dog Bruce is our little escape artist! He's always trying to figure out ways to get out of are backyard! He loves to have us run after him for 20 minutes at top speed(always just out of our reach) and then just sit down and look at us like he's saying ok I had my fun take me home. It gets really annoying after a while! I've tried everything! Treats, toys, come, but he still won't listen. He'd rather chase a rabbit than get a treat! If he's fenced in he can do come but if he's out in the open he will bolt! Any suggestions?
