Fergie, also known as Lady Ferguson of Readington, is a Cavalier King Charles Spaniel belonging to Dr. David Costlow and his family. This regal pup is terrified of swimming but loves the lake. Her ideal vacation is spent on the Costlows' boat, but more than anything, she loves a good ride on the waverunner. After a long day on the lake, Fergie likes to cool off with an ice cold beer.
