The only thing that I see that is different about Iggies and Whippets are that Iggies are waaaaaaay more hyper than Whippets. Cooper was a rescue found on the streets in San Antonio which made him scared of a lot of things when we first got him. Now the only thing he has a problem with is the need for attention. When I bring him home from college and he is around Lexie he believes that he should have all the attention and gets nervous when he doesn't have it. For the most part Iggies and Whippets are similar in their personalities. Both love sleeping, running, playing, and being in your lap 24/7.
