Here's a precursor to David Lynch's comic strip "The Angriest Dog in the World," about a dog "so angry he cannot move; he cannot eat; he cannot sleep; he can just barely growl; bound so tightly with tension and anger, he approaches the state of rigor mortis."  This vintage angriest dog appears in Johns Hopkins' 1895 yearbook.

From Lustige Blätter, 1899.

"Disengage yourself at oncely; this seat are occupied."  From the Ellendale yearbook of 1915.

"Tell It to the Dog.  The Traveler said, 'Glad enough to see you, pup,' and knelt and caressed the little animal with his big, gentle hand."  From Cosmopolitan (1919).

"Forlorn dog strangely attracted to squirrels -- on wheels."  From the Florida Flambeau, 1959.

At first glance we thought that mirror in the background was a giant soap bubble.  May it sort of is.  From Lustige Blätter, 1918.
