"According to Shuar belief, dogs are a blessing from the earth mother, Nunkui, while Quichua view canines as gifts from forest spirits that can protect against mal ojo, the evil eye. And when their dogs become ill, these tribes use the plants around them as veterinary medicine. For example, ficus helps fight parasites, and Anthurium eminens treats botfly infections. In other cases, a mix of tobacco and ginger applied to the eyes can allegedly help dogs become better hunters by improving night vision. Dogs are so sacred in such societies that some peoples will even give them psychedelics. Surprisingly little is known about this practice, only that it dates back several centuries and those who do it believe it to be beneficial."
