Dogs should not be allowed to wear boots all the time. Remove the boots every hour or two so that air can cool down your dog's paws. Dogs have their sweat glands in their paws so keeping the boots on for a longer duration may make your dog uncomfortable and can cause chafing due to friction and rubbing. Also, before putting the shoes back on, make sure that their paws are completely dry to avoid foul smell and infection due to bacteria build-up.
