If they cause excess heating or are left on for too long, they can cause burns. Dog heating pads are a blessing for dog owners, and you, as a dog owner, can lay your dog to make it feel comfortable when the temperature falls during winter. The safety of a heating pad depends on the quality of the product.  If the heating pad gets overheated, it might leave burns on your dog’s body. So, it is ideal that you do not let your dog lay directly on the heating pad to prevent skin burning.
