When you're out camping, it's important to be dutiful when it comes to picking up after your pet. Pack plenty of doggie bags, and keep an eye out for when your dog goes.
Dispose of the waste afterward in a garbage bin or other designated container. You don't want to leave it lying around where other campers -- or your kids -- can step in it.
If a receptacle isn't available, the next best option is to bury it, so you may want to bring a little folding shovel dedicated to the task.
