We take our 2 lab mix puppies (less than 1 yr old & about 60 lbs each) on our trips. We have yet to leave them alone for long & never when it was hot but found an interim measure to reassure ourselves that they are good campground neighbors. We are using voice activated Walkie talkies. As long as we aren't too far away, we can hear them if they bark and even talk to them to calm them. Not a solution for the temp issue but we can use the auto start if the power goes out. We also have a camera we are planning to set up. Doing our best to care for the baby boys & still be neighborly.
