Oh man, this would freak me out!.. Being from Hawaii, and when I had Spike, I never worried about this sort of thing.. Now a few times, he cut him self to the bone on busted glass and ran a mile at full sprint to the omega station where he had no more paw pads left. See those white socks, they were red. Then I had to take him home and bandage up my big oaf hound.. I can't believe that guy! Loyal to the end. I miss miss my big oaf hound!!!
