A US dog breeder has filmed adorable video of a litter of Scottish terriers circling around a bowl of milk in a manner that resembles a pinwheel. The six pups are 10 weeks old in the video uploaded earlier this month to YouTube, and have been drinking milk in such a fashion since they were half that age. The dogs are purebred Scottish terriers from champion and working terrier lineage. "While their mother is a black Scottie, like them, the sire is a Wheaten colored Scottie," their Colorado breeder told ninemsn. "The puppies are all spoken for, one going to Louisiana another to Utah, another Colorado, and so on. One will stay with us to carry on our lineage."
