Safe and Natural Made from a blend of several food-grade waxes, then refined according to our our own special formulations, Musher's Secret is the safe, non-toxic way to protect your dog's paws. The semi-permeable shield is absorbed into the paws, allowing perspiration to escape through the toes. Made from 100% safe, non-toxic natural waxes and easy to apply! Spread a light coating of Musher's Secret on the pads and rub in. Mushers will absorb in minutes (rub a little on your hands, when it is absorbed you will know it is absorbed into the pads as well). We use an old rug near the door for application purposes. In very harsh cold or snowy conditions be sure to rub up in between the pads to prevent snowballing. For year round use, 1-2 times a weeks is sufficient. During extreme weather additional applications may be necessary. Frequency may depend on length of your walk and weather conditions.
