Chappy, by way of Ann and Don Oldenburg

If shaggy purebred Tibetan terrier Chappy looks more at home nuzzled into the overstuffed living-room couch than nosing around the newest nature trail at a dog-friendly park, it's because he is. At 11 years old, Chap's not nearly the spry pup he once was, and doesn't move as briskly as he did when researching for the first edition of The Dog Lover's Companion to Washington D. C. & Baltimore in 1998. His left hind leg gets a little gimpy at times and he needs to catch his breath more often.

Don Oldenburg was born and raised in the Washington metropolitan area with a loyal black cocker spaniel named Inky.They live with their three baseball-playing sons, J.B., James, and Cole, in McLean, Virginia.
