We have two Samoyeds...we pullthe shades...put on soft music...turn the lights off...and leave them to snooze in their crates. They actually look forward to it because they know whenever they go into their crates and we close the door...they get a treat.
We also have a monitoring system in the camper that will call us if the temperature gets above our alarm set point...or if the power goes out. It's simply a pay as you go cell phone, PhoneLynx Bluetooth bridge, and an Intermediate Freeze Alarm. We can also call into the camper from wherever we are and get a report on the current temperature etc...
