Dog crate covers come in various fabrics and designs – some are made from insulating materials, others are constructed of thin and lightweight fabrics. So, how well a kennel cover will be able to keep your pup warm depends first and foremost on its build materials. Besides this, where you keep the crate also matters – if you’re keeping it in the house, the cover will most likely be able to keep your pet warm no matter what it’s made from. Where the build materials become very important is in the outside conditions. If you plan to use the cover in cold, rainy environments, a thin and lightweight cover won’t do – your pup will need a thick, water-resistant and well-closed cover to keep them warm, possibly an insulated one if the temperature is very low and is snowing.\r
