In the Pampas of Buenos Ayres the traveller meets with European dogs, which have become wild. They live gregariously in holes and excavations, in which they conceal their young. When the horde becomes too numerous, several families go forth, and form new settlements elsewhere. The European dog barks as loudly after it has become wild, as does the indigenous American hairy species. Garcilaso asserts that, prior to the arrival of the Spaniards, the Peruvians had a race of dogs called _Perros gozques_; and he calls the indigenous dog _Allco_. In order to distinguish this animal from the European variety, it is called in the Quichua language Runa-allco, Indian dog, or dog of the natives. The hairy Runa-allco appears to be a mere variety of the shepherd’s dog. It is, however, smaller, has long yellow-ochry coloured hair, is marked with white and brown spots, and has erect and pointed ears. It barks continually, but seldom bites the natives, however it may attack the whites. When the Inca Pachacutec, in his religious wars, conquered the Indians of Xauxa and Huanca (the present valley of Huancaya and Jauja), and compelled them by force to submit to the worship of the sun, he found that dogs were made the objects of their adoration, and that the priests used the skulls of these animals as wind instruments. It would also appear that the flesh of this canine divinity was eaten by the believers.[CX] The veneration of dogs in the valley of the Huancaya is probably the reason why the skulls, and even whole mummies, of these animals are sometimes found in the Huacas, or Peruvian graves of the most ancient period. Von Tschudi, the author of an admirable treatise on the _Fauna Peruana_, has examined these skulls, and believes them to belong to a peculiar species, which he calls _Canis ingæ_, and which is different from the European dog. The Huancas are still, in derision, called “dog-eaters” by the inhabitants of other provinces. Among the natives of the Rocky Mountains of North America, cooked dog’s flesh is placed before the stranger guest, as a feast of honour. Captain Frémont was present at such a dog-feast in the neighbourhood of Fort Laramie, which is one of the stations of the Hudson’s Bay Company for trading in skins and peltries with the Sioux Indians.[CY]
