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.
