I was speaking dogs in general. Police dogs work on every kind of surface without boots. My shepherds are strictly indoor dogs also In summer they go 4 miles on hot pavement for exercise with no ill effects.
Dogs in Florida are also on hot pavement and there are lots of Shepherds where we go. Not putting boots on a dog doesn't mean someone doesn't care, it just means the dogs have tough feet. To quote a friend...if you can't stand the heat etc.... Chill Nicole no one is accusing anyone, this is a public forum.
