Origin of "hot dog"

[George Thompson]

Douglas G. Wilson observes: "In the 19th Century, sausages were
associated with dogs (NOT dachshunds!)in two ways: (1) "dogs like
sausages" (a sausage was considered an appropriate treat for a dog, and
the stray-dog population was routinely suppressed by means of poisoned
sausages in some cities); (2) "sausages are made out of dog meat"
(partly humorous)."

"Dog meat" might mean either of two things: the meat of a dog or meat
only fit for a dog: scrap meat gleaned by a butcher from here and there
on a carcass.  Presumably that's the sort of meat sausages are made
from, but there is humor to be had in pretending that a sausage is made
of meat from a dog.

Does anyone remember the uproar of 20 year ago, or more, when it was
found that some American hotdogs were made in part from kangaroo meat?
