While the minimum temperature that you can safely take a dog camping varies tremendously by breed (and age), it's best to start with camping trips where the nighttime temperatures aren't projected to fall below fifty degrees Fahrenheit. If you're concerned that your pooch will be cold, there are several things you can do to make them more comfortable. The first is to ensure that your dog is insulated from the cold of the ground by getting them one of the best backpacking sleeping pads with an R rating. Many closed-cell foam mattresses provide an R rating of 2 or higher, which is appropriate for summer camping. The next strategy would be to ensure you are sharing some body heat with your dog overnight by allowing them to curl up next to you (something they'll be inclined to do anyway inside of a cozy tent). Keep in mind that, more often, dogs struggle with the heat while car camping more than they do the cold. Have plenty of water and shade available for your pooch, and encourage them to rest with you during the heat of the day.
