Grip Trex shoes give dogs flexible rubber traction and paw protection on hot pavement, sharp scree, and winter salt. They are more substantial than soft disposable booties and meant for real outdoor miles.
Important buying note: Ruffwear sells these in pairs (2 boots), not sets of four. Order two pairs — and often mix sizes if front and rear paws differ.
Measure paw width carefully and practice indoors; most dogs high-step for the first few sessions before the gait normalizes.
