I own two pieces Ororo's heated apparel for myself, which have absolutely gotten me through this wickedly cold WNY winter (2026). I absolutely feel terrible for my small dog, who absolutely hates being cold. Fortunately I saw this vest is available for dogs! The same great quality and reliability but for a dog. The vest came smartly packed, with the battery and cord. Same as the human gear, the vest has the hot/warm/cool mode and color indicator. The vest is easy to slip on and was easy to size to my dog. The only tricky part are the elastic loops to secure the back to the hindlegs. It only took a few steps, but Jedi has gotten use it. Although I love the idea, because it holds the vest snuggly to the dog.
