1852  [The sailmakers had to make . . . two pairs of canvas "boots" for each dog, to protect their feet from the rough ice, after being several days out.]
1871  (1883)  The dog-boot is simply a fingerless glove drawn on over the toes and foot, and tied by a running string of leather round the wrist or ancle of the animal; the boot itself is either made of leather or strong white cloth. Thus protected, the dog will travel for days. . . .
1942  The little pups never did any asking, and when at last it was absolutely necessary, Bob simply caught them and forcibly held them when he tied on the leather dog-boots.
