I've used this for a little less than a month. I used it for my cat, but it can also be used for dogs. The cover has some fuzz and shows some signs of use. The heater and cord parts are not a problem. This is a fleece-covered pet hot carpet. - It protects the heater and power cord to prevent pets from biting. - A thermostat is located inside to maintain the carpet at the appropriate temperature and cut down on unnecessary power consumption. - The main body has two sides: a high-temperature side (approx. 38°C) on the front and a low-temperature side (approx. 28°C) on the back, allowing you to choose according to the climate and your pet's condition.
