The most common type of injury caused by pets is urine burn on shrubs (see animal urine).
Occasionally other types of injury occur. Girdling can be a problem if dog chains are tied around a tree trunk. As the animal pulls the chain around the trunk, the chain wears the bark and girdles the tree. Horses, goats and sheep will sometimes eat the bark from trees. Cats may use young tree trunks to sharpen their claws. Girdled plants usually die.
