I have two small chihuahua mix dogs and they absolutely love this bed warmer. It actually keeps them in bed and calm through the night and during stressful times when I am gone. It is warm to the touch and really heats up the bed when you use it. I would recommend using it with a bed with a liner you can unzip so you can put the warmer inside. This way, the whole bed gets cozy and your dog will stay warm and comfortable.The amazon price is great as my local pet stores are selling these for close to $50.
