The park we are in right now, has a strict leash law, but also has a 75 pound size limit. Lucky for me we have two nice off leash parks within a mile of us. So Max gets to run off leash at least twice a day. And as anyone who has ever had a Lab knows, a tired Lab is a happy Lab is so true. While we host at state parks we leave Max outside usually chained to something that will offer some sun and plenty of shade and water. He has choices, and is perfectly content watching squirrel's and people until we return. No matter what, all dogs should go through obedience training to learn to be good citizens. Far too many people want to ignore the rules because their little mutt would not bite or attack.
