Okay so Clyde walks pretty well on a leash when we are on public trails. When we go to the dog park he takes off at like 40 mph exploring the park and I see him looking for me like every 5 minutes. This summer we will be camping and hiking trails a lot. I would like to let him off leash when we are in more remote areas but I am afarid he will he running off like he does at the dog park. I see other V's that sort of walk along side their owners while they are off leash. How do I get him to do that? He will be one on June 1.
