One fellow with a large dog uses a small shovel, removes his sewer connection and dumps it there. Another places it in the toilet and sends it to his black water tank. Whatever works for you, it's absolutely necessary to pick up after pets. However, whenever we take her for a walk we always carry a plastic sandwich bag, just in case. Costing about 79 cents for a box of 150, the cheapest ones are fine for this purpose.
Nobody wants to be awakened early by a barking dog or for that matter to hear one barking at all.
It's one thing for a pet to bark when someone knocks on the door, somehow I don't think dogs can be trained not to do that. It's quite another to hear one howling when their owners are away from the RV, or barking at anyone walking down the street. Let's face it, pets onboard an RV aren't often there for protection, they're for companionship. Even if you might have a larger one for protection when boondocking in isolated areas, it's necessary for them to be reasonably quiet when in an RV resort or campground. After all, that's our neighbors front yard, not hers.
