Perhaps Midwest should officially announce that the Premier Pet Program no longer exists as it continues to get frequent mention in the media.
During the last two days alone, Midwest Airlines and pet travel were highlighted in several places, including:

Every time I look at my Google news alerts for Midwest it's amazing to see how much interest this program still generates. It's generally positive (and free) publicity for the airline.
Like mke9499, I'm also curious as to what happened with the program.
