An Australian review of existing studies has argued that the environmental impact of owned dogs is far greater, more insidious, and more concerning than is generally recognised .
While the environmental impact of cats is well known, the comparative effect of pet dogs has been poorly acknowledged, the researchers said.
The review, published in the journal Pacific Conservation Biology, highlighted the impacts of the world s commonest large carnivore in killing and disturbing native wildlife, particularly shore birds.
In Australia, attacks by unrestrained dogs on little penguins in Tasmania may contribute to colony collapse, modelling suggests, while a study of animals taken to the Australia Zoo wildlife hospital found that mortality was highest after dog attacks, which was the second most common reason for admission after car strikes.
In the US, studies have found that deer, foxes and bobcats were less active in or avoid wilderness areas where dogs were allowed, while other research shows that insecticides from flea and tick medications kill aquatic invertebrates when they wash off into waterways. Dog feces can also leave scent traces and affect soil chemistry and plant growth.
