Running A/C while driving

IIRC, most all of the CGs we visit have a "Do Not Leave Pets Unattended" rule. Now whether this means inside or outside, I don't know. What I do know is that at Petit Jean SP in AR, a family across from us left their small dog and a cat inside while they went off for the day. The poor dog barked, screeched and cried all day....not to mention that they shredded the blinds and Lord knows what else inside. Being "dog people" we were more concerned for the pets that what damage they were doing. "dog people" can turn off the sound of barking when they know the pet is freaking out. As totally non-destructive as my beloved Sam was, and now Foxy, I would not even consider for a second leaving them loose in the trailer and likely not even in a crate for any barking that would disturb others nearby.

When we know that we're going to be going out for a long day or even taking a much longer trip that we'll be in and out, we leave our camping dog home. Re the hot car?? NO!!! If you don't have a neighbor who will feed and tend to your dog for a few days, your other choice is to board them and consider the cost just part of your camping weekend.

Also consider how blasted hot that trailer is going to get if the power should go off and you're gone for several hours. Coming back to find your pet dead from the heat would pretty much ruin your fun day out.

I have heard of folks who have been asked to leave when they returned after leaving a barking dog alone.
