All right, so I was browsing the OmniGroup website, and came across the "Pet Testimonials" at the bottom of this page. They are all rather silly, but I was particularly intrigued by the testimonial of the dog "Oslo". So I did a quick Google search, and it turns out that Oslo's claims are true! These dogs actually can bend their heads back 180 degrees, they can close their ears, and they have six toes on each foot. More info here. While reading that site, I saw this photo and was unable to stop giggling for about 10 minutes: Has anyone ever seen or had one of these dogs? They sound fantastic!
