My problem: Our yappy little dogs

Do your dogs bark when you leave them alone at home? If not, then keep the window shades down, leave the radio on loud enough to mask outside noise, and keep a fan on to provide white noise. If your dog likes the t.v. on, put that on instead of the radio. If your dogs are barkers when you leave them, even at home, then yes, it will likely be a problem in a campground. Nothing worse than a non-stop barking dog, IMO. I used to use a bark collar on my little dog because she used to be a barker in our camper when we first started taking her along. Now, I just lay the collar next to her crate when we leave, and she doesn't bark anymore. Yes, I crate my little dog when she's left alone. It encourages her to sleep and keeps her out of trouble.
