RECOMMENDED WEIGHT: The boot is made of wool with a soft lining that respects the paws. The soft sole is made of soft particles. With good anti-slip effect, it provides traction and protects dog’s paws from injury from pavement, grass and tiled floors on surfaces such as patios, boats, winter salt, snow, ice, indoor hardwood floors, and also provides treadmill traction or execution. Easy to Wear: Easy and quick to wear, but not easy to fall off. These boots feature closed controls, wide flexible and adjustable bands and relatively flexible and roomy night safety reflexes for a better fit. If your dog’s paws are between the two sizes, try using socks over the boots if you go for larger paws. Note: Please note that this shoe is ideal for shoes indoor and sunny steps. Colour: Red, Size: 4.5 x 3.5 cm.
