Best Practice to tie up dog?

If the dog doesn't leave you, then just sit outside with it's leash on and loop the handle end of the leash around a chair leg. If it's as you say, you don't need the chain to restrain the dog and it should just sit next to you on the ground.That is what our dog does. Most campgrounds we have been to do not allow campers to leave their animal unattended outside. One reason - barking and the other is it makes them vulnerable to any prey - coyote, rabid animal, stray dog etc. Also a chain will damage trees and most owners will not like that.
