Hi Newbee, it’s pretty much the same as leaving your dog at home while you’re at work except your home is an RV. If you park in an RV park, you may be able to set up a fenced in area around or to the side of your RV that your dog could hang out in while you’re gone, depending on the weather, or if the temps are more extreme you can leave him inside. Dogs in general like smaller spaces anyway.
I’ve never heard of doggy day care at RV parks however you could always hook up with someone who has a dog at the park and trade watching them.
Best of luck! Don’t fret too much about the dog situation. They’re incredible adaptable and I bet he’d love to see you relaxed or excited about a new living situation 🙂
