Border Patrol substations located on the Tohono O’odham nation inside the state of Arizona are very remote and will often have “Reservation Dogs” in the encampment; dogs which have friendly and approachable dispositions and who are loosely adopted and fed by the agents who in return help guard against rattlesnakes or scorpions. These dogs are free to come and go and will often bring into camp the bones of remains from other animals to chew on.
