What breed of dog appers in cigna commercial?

Interesting, I was just watching the latest Cigna Commercial and had the same question about a dog that appears in it. It resembled a basset hound, dalmatian, dachshund, and a beagle. Strangely enough a small segment that would otherwise be insignificant has individuals discussing, searching and repeating the organization's name. Well done marketing agency of Cigna, well done.
