The character, sensibilities, and intellectual faculties of animals have always been a favourite study, and they are, perhaps, more strongly developed in the dog than in any other quadruped, from the circumstance of his being the constant companion of man. Of all the propensities of the brute creation, the well-Page 5known attachment of the dog to man is the most remarkable, arising probably from his having been for so many years his constant companion, and the object of his care. That this propensity is not instinctive is proved, by its not having existed, even in the slightest degree, in the Australian dog.
