What an incredibly cute  puppy! This is Casey  with one of his very best  new friends  in the whole world, Pat Engle. Casey  is a Yorkshire Terrier puppy who was born on  June 11, 2003, and  is shown here t his first Puppy Plan appointment on September  9th when he weighed 4.8 pounds. Pat tells us that she and her husband, Gene, love to watch this fun puppy as he runs laps around their living  room and then desperately tries to jump up on the couch. The level of energy that some of these puppies have is amazing!
