up to 80%. As one of many clothing products made from animal skin, sheepskin boots have been the subject of criticism by the animal rights movement, and producers have responded by improving animal welfare. Animal rights groups call for the boycott of sheepskin boots and their replacement with synthetic alternatives. In 2007, Pamela Anderson, realizing that the boots were made of skin, called for a boycott on her website. In February 2008, the Princeton Animal Welfare Society staged a campus protest against the fur industry, particularly attacking the sheepskin boot industry. Trademark disputes The trademarking of the UGG name has been the subject of dispute in several countries. Deckers Outdoor Corporation has won disputes in the United States, the Netherlands, and Turkey. In Australia and New Zealand, ugg is a generic term.

Deckers' law firm Middletons of Melbourne began a serious effort to halt the Australian companies' sales by sending cease and desist letters to a number of Australian and U.S.-based manufacturers, preventing them from selling sheepskin boots using the UGG trademark on eBay or from using the word in their registered business names or domain names. Deckers initiated numerous domain name actions under the UDRP. In response to these actions by Deckers, some Australian manufacturers formed the Australian Sheepskin Association to fight the corporation's claim, arguing that "ugg" is a generic term referring to flat-heeled, pull-on sheepskin boots. One of these manufacturers, Perth's Uggs-N-Rugs, who had been manufacturing ugg boots since 1978 and selling them online since 1996, appealed to Australian trademark regulators. The officer who heard the case stated that the "evidence overwhelmingly supports the proposition
