Are Dogs Colour-blind?
[Jan. 12, 1884.]
Your correspondent, "W. H. O'Shea," has found several dogs
"colour-blind," If black is a colour, I can give several instances in
which a black retriever dog of mine was certainly not "colour-blind."
He had the greatest antipathy to sweeps and coalheavers, and would fly
at them if not fastened up or carefully watched. He would even bark at a
passing hearse! In all other respects, he was the best-tempered dog in
the world, and I can only imagine that when very young he must have been
ill-used by either a sweep or a coalheaver.
