Hydrophilic fleece dog bag with zip along back seam designed to keep dirty paw prints from entering your home and car. Will also dry your dog after a walk or bath. Due to size variances within each breed WeatherBeeta strongly recommends that every dog is measured before a bag is purchased. Step 1: Length Place a measuring tape at the base of the neck, measure along the spine and stop at the base of the tail. Step 2: Height Measure from the base of the neck to the dogs feet. Step 3: Neck Measure the circumference of the pet’s neck for a snug fit.
