W. N. Hutchinson, Dog Breaking
“ It is quite astonishing how well an old dog that retrieves knows when a bird is struck. He instantly detects any hesitation or uncertainty of movement, and for a length of time will watch its flight with the utmost eagerness, and, steadily keeping his eye on it, will, as surely as yourself, mark its fall. To induce a young dog to become thus observant, always let him perceive that you watch a wounded bird with great eagerness; his imitative instinct will soon lead him to do the same. This faculty of observation is particularly serviceable in a water retriever. ”
