Many people take their dogs along for the ride in the back of their truck and many, many of them have the black truck bed liners in the beds. The majority of the people that let their dogs ride in the back never stop to think how hot those bed liners get on a sunny day just on moderate spring days. And then on summer days the liners get unbearably hot. Those liners can cause quick heat strokes in dogs and can actually burn a dogs foot pads! So PLEASE, if your dog rides on a black bed liner make sure you put something light colored down to insulate against the inhumane temps of those bed liners. It just might save your dog from severe injury or even death!
