Give your snowbound pup a boost with Granite Gear's Mush booties.
Granite Gear's Mush booties for dogs are designed for increased traction on snow. They utilize the same ergonomic design and materials as Granite Gear's Endurance Dog Boot with the exception of the sole, which is built with the same fabric used in climbing skins for backcountry skiing. They mimic the natural directional texture of a dogs paw. Run a finger across the pad from front to back and the pad feels smooth, run your finger from back to front and you can feel the grip, just like climbing skins! Sold in pairs. Medium fits paws 2.5in to 3in, Large fits paws 2.75in to 3.5in, XL fits paws 3.25in to 4in. -Vendor
I bought these booties for my boyfriend's dog (Labrador Retriever) to wear when she was accompanying him on a hike in the white mountains. They didn't even make it a day before they fell apart. I wouldn't recommend them for a really active dog.
Even though i own a sleddog whose paws are made for winter, I still use these to prevent dry, cracked pads. They would be good also for long treks across sharp rocks. It does take a short while for the dog to get used to them.
