Dog booties can really protect their pads ( bottom of there feet) from getting cut of scraped or getting infected. I t also helps stop them from digging...
Dog wear booties when they run because rocks, roots ,mud and snow or ice can be torturous on their feet causing stone bruising, cuts and blistered pads.
Mushers put booties on their dogs so they don't get scraped on sharp surfaces. no it ain't its cuz they don't want em to get cold cuz they can get sick and junk and like they could loose or somethin
