"A couple of years later, Warhol and Johnson decided to expand their clan, acquiring another (light brown, shorthaired) dachshund, Amos, to keep Archie company. "Unlike Archie who enjoyed the company of people and was very social, Amos was more like a regular dog," Fremont remembers. At this stage Warhol ceased to take his dogs out on the town, happy in the knowledge that they would entertain each other at home." http://www.anothermag.com/current/view/2913/Andy_Warhols_Cats_and_Dogs
