Difficulties with Pets and RVing

As I got my trailer a few years after I got the dog, she is not used to traveling. I tried to take her a couple of times, but she is more comfortable at home. Dogs like consistency and routines--at least my lab does. I'd reserved a space at a campground for a month and took her for a 4-day stay. She is not used to being on a leash or tied up (CG rules), and was well-behaved, but I couldn't leave her to even walk a few feet to the camp store--she became very anxious. And rightly so-she was in a completely new environment and felt insecure. it wasn't fair to her. She loved being able to swim and loved that part. However, she wasn't used to being walked on a leash to 'do her business' and didn't poop for 3 days! She was used to roaming a huge backyard. So now I leave her at home (I have an adult son who stays at my house while I go camping). The dog is happy and I am, too.
