European dogs have become wild in the grassy plains or Pampas of Buenos Ayres. They live in society, and in hollows in which they hide their young. If the society becomes too numerous, some families detach themselves and form new colonies. The European dog, which has become wild, barks as loud as the original American hairy race. Garcilaso relates, that before the arrival of the Spaniards the Peruvians had dogs, “perros gozques.” He calls the native dog, Allco: it is called at present in the Quichua language, to distinguish him from the European dog, “Runa-allco,” “Indian dog” (dog of the inhabitants of the country). The hairy Runa-allco seems to be a mere variety of the shepherd’s dog. He is small, with long hair, (usually of an ochry yellow, with white and brown spots,) and with upright sharp-pointed ears. He barks a great deal, but seldom bites the natives, however disposed to be mischievous to the whites. When the Inca Pachacutec, in his religious wars with the Indians of Xauxa and Huanca (the present valley of Huancaya and Jauja), conquered them, and converted them forcibly to the worship of the sun, he found them paying divine honours to dogs. Priests blew on the skulls of dogs, and the worshippers ate their flesh. (Garcilaso de la Vega, Commentarios Reales, P. i. p. 184.) This veneration of dogs in the valley of Huancaya is probably the reason why skulls and even entire mummies of dogs have been found in the Huacas, or Peruvian graves belonging to the earliest epoch. Von Tschudi, the author of an excellent Fauna Peruviana, has examined these skulls, and believes them to belong to a peculiar species of dog which he calls Canis ingæ, and which is different from the European dog. The Huancas are still called derisively by the inhabitants of other provinces, “dog-eaters.” Among the natives of the Rocky Mountains, cooked dog’s flesh is set before strangers as a feast of honour. Near Fort Laramie, (one of the stations of the Hudson’s Bay Company for the fur trade with the Sioux Indians), Captain Frémont attended a feast of this description.
