The caption of this sketch by James Thurber says "He's in love with a beagle who moved away" and the dog has a tear falling. This sketch is in the book below.
What a fun book to read; stories by James Thurber about his dogs, and his simple whimsical drawings. The book is "The Dog Department: James Thurber on Hounds, Scotties and Talking Poodles", edited by Michael J. Rosen. I treated myself and bought a copy at thriftbooks online. A favorite story is The Thin Red Leash about how Thurber's Scottie puppy was insulted by some large and menacing workmen, while on a walk with Thurber. He thought that might be the day to die in defense of his pup, when an even larger man stepped in and loudly praised the pup. Thurber calls the man "the train lifter" because he looked strong enough to lift a locomotive from one track to another.
Another Thurber sketch from the book and this one needs no caption.
I found the above book when reading "Dogs We Love", also edited by Michael J. Rosen. Jane Smiley, Armistead Maupin, Edward Albee, Ann Beattie and more contributed stories about their dogs. This book was a Christmas gift to me from my younger son, and has excellent photos in it.
If you love dogs and humor and essays about people's dogs you may enjoy these books as I do.
