It seemed the subject was much harder to circumscribe than we at first thought. Our friend Julie used the word stray dog I said wandering dog and we debated on which term would fit best.
Shared loneliness in a cruel world IntroductionĪ while ago, our friend and we were discussing the tricky problem caused by all those abandoned and loose dogs wandering about in our village.

Dogs are important reservoirs of this parasite. Particularly notable is the high incidence of filarial heartworm in several species of mammals, including the local human residents. Field studies on distribution, demography, behavior, and disease transmission also began on Isla lsabela in 1981. Control rests primarily on carefully placed flesh baits poisoned with Compound 1080 (sodium monofluoroacetate]. To counter this problem, a coordinated eradication and study program on all dog populations has been underway since 1979, and an eradication program on Isla lsabela, begun in 1981, continues with marked success. The chief targets have included land and marine iguanas, tortoises, and colonially nesting marine birds.
While other introduced mammals (chiefly feral cattle and pigs) have served as prey, in recent years severe depredations on the unique endemic Ga/apagan fauna have been caused by the dogs. Feral and pariah dogs are both scavengers and predators. Problems derived from their presence are most apparent on the islands of Santa Cruz and lsabela. For example, domestic dogs intentionally introduced now exist as three major types: domestic, free-ranging or pariah, and feral. Several species of mammals introduced onto the Galapagos Islands illustrate this ecological axiom. Organisms introduced onto insular ecosystems, after they have become established, frequently increase to destructive numbers.
