By Air – Many airlines will not ship animals during summer months due to dangers caused by hot weather. Some will only allow dogs to fly in the early morning or in the evening. Check with your airlines for specific rules.
If you do ship a dog, put icepacks or an ice blanket in the dog’s crate. (Two-liter soft drink bottles filled with water and frozen work well.) Provide a container of fresh water, as well as a container of frozen water that will thaw over the course of the trip.
By Car – Keep your dog cool in the car by putting icepacks in his crate. Make sure the crate is well ventilated.
Put a sunshade on your car windows.
Bring along fresh water and a bowl, and a tarp or tent so you can set up a shady spot when you stop. Keep a spray bottle filled with water to spritz on your dog to cool him down.
By RV – A dog’s safety should not depend on the air conditioning and generator systems in an RV or motor home. These devices can malfunction, with tragic results.
If you leave your dog in an RV with the generator running, check it often or have a neighbor monitor it. Some manufacturers have devices that will notify you if the generator should malfunction.
Never leave an RV or motor home completely shut up, even if the generator and AC are running. Crack a window or door or run the exhaust fan.
