I go any weekend I can. My son is 25and lives south of town. So when I am heading that way I always tell him. When he is not working he usually goes with. I can only take Max (11 y/o) when its over 50 degrees out. Titus(8 y/0) can go a little colder, but only when its dry. The only danger Titus causes is wanting to go potty at the cache site...we always tell him no they don't want us to leave that.
I am going to order tags for the dogs that have a "tracking Number" on them. Then people can "Log my Dogs" as a mobile find. Here is the link to that tag. I love it.
