Leaving dog at campsite

We leave our two when necessary in the fiver. To make sure all is ok we have a Amazon Cloud Cam with audio on the entire time we are gone as well as a temp stick to monitor temp and humidity. We also use a Verizon mifi rather than rely on cg internet connections. Both my and my wife's smart phones are set up to receive text and emails from the temp stik if something goes haywire. They are not and never have been crated but that is just our preference.
Leaving your dog outside will cause you a lot of problems in most cg's if the dog is not attended.
