Our "three amigos) three Chihuahuas always go with us. When we leave them we have the air on or heat on (depending on the weather) and we also leave a radio or TV on low to keep them soothed. We carry a fold up crate and two sleep in it at night and they have made this their safe house and one sleeps with us. We also carry two of the fold up metal pet fences, hook them together and they have a play pen to use when we are at the TT, make is easier to clean up the poop and less trouble at feeding time. We have found most most CG's are pet friendly and as stated some do have a dog type limit usually larger or more agressive dog types. Fla, state parks are per friendly except they are not permitted in some areas of the park, and have to be on a 6" leash but for other CG's if fact they are so pet friendly we actually took a 2 week old bottle baby goat once and it was the hit of the campground, especially with the children it is a good idea to ask before making reservations.
