Here's an example..."Free-roaming dogs can especially cause harm on islands, where ecosystems tend to be vulnerable in the face of non-native predators like dogs. For instance, in the late 1980s, researchers found that a single German shepherd on the loose in New Zealand's Waitangi State Forest was responsible for killing up to 500 kiwis. The dog had a collar, but was unregistered, and its owner was not found.
In another example from 2006, 12 ownerless dogs were thought to be wiping out populations of the endangered Fijian ground frog on the tiny Viwa Island. The Fijian villagers' solution was to "befriend" the dogs by feeding them scraps of food. Ten of the canines were eventually tamed and shipped off the island and the remaining two were killed.
The researchers note that much of the scientific literature on the problems posed by dogs focuses not on conservation issues, but health risks to humans. While canine rabies has been eradicated in the United States, dogs are responsible for nearly all of the 55,000 rabies deaths that occur worldwide, mostly in Asia and Africa. And rabies can disrupt wildlife, too, the researchers said, noting that dogs have been blamed for spreading the disease among several other animal species in Africa, including the extremely rare Ethiopian wolf .
"Despite the increasing recognition of the potential problem dogs may create for wildlife, few solutions to conservation issues were offered by the literature reviewed, particularly to non-disease related problems," Hughes and Macdonald write. "Local people and authorities may be reluctant to undertake dog population management or control because of the close nature of dog-human relationships, aversion to the methods that may be used to remove dogs" — like poisoning and shooting the feral ones — "lack of adequate alternative care options, and perceived prohibitive costs of action."
Their research was detailed last month in the journal Biological Conservation."
