This illustration shows a typical family portrait session with an old bellows camera, but with dogs in the place of people.

No. 4 Marcel Schumann Importers, 1355 Market Street, San Francisco, Calif.
There is no description on the back of this card.
Again in this image, the dog photographer has no pants, though the ‘father’ dog does, consistent with the rest of his formal attire. This ‘father’ dog also appears to have hands instead of paws, judging by the way they have been drawn next to the infant dog on his lap.
This card likely dates from the 1940s.
