While some animals, unfortunately, suffer from paw pad burns due to being in a fire or chemical irritants, other dogs can get burnt paw pads from walking or running too hard on hot pavement or flat surfaces like tennis courts. Hot pavement and rough surfaces or terrain should be avoided, especially when healing. Check surface temperatures before walking your dog. Hot pavement should be avoided, as well as severe ice, snow, or areas with salt to melt ice. The length of time a paw pad burn will last depends on the dog and the extent of their injuries. Mild injuries may heal within 7-10 days, while severe burns and pad sloughing may require weeks to completely heal. Physical burns can occur when surfaces are too hot, but dogs can also have a burn or blister from running on surfaces they are not accustomed to, like concrete. Commonly, hot concrete or pavement causes blisters on the pads that can fill with fluid and rupture a few days after the exposure.
