The Great Dane, a goat and a three-legged retriever rescued and cared for by Eastlake Veterinary Hospital, 10101 E. Northwest Highway, are getting an extension on their 15 minutes of fame Friday at 8 p.m., when the National Geographic Channel airs a feature called Unlikely Animal Friends. The trio — two of which were runaways and the third unable to be cared for by its owners — have appeared in the DMN and on local TV. Now they’re apparently ready for national and international exposure.
