The best way to instill good manners is to practice them everywhere you go, making sure your dog understands the same rules apply no matter where you are. Titan practiced following me around new distractions at Lake Benson. He stopped to sit on bridges, holding that sit until released. He held a long distance down in front of the lake and took in the beautiful scenery. On the trails he practiced a little bit of agility by jumping over fallen trees. A walk like this makes for a nice tired dog when you come back home!
