A puppy or adult dog (preferably adopted from a shelter) that a couple (usually Caucasian) gets shortly after marriage as "test case" for how they will manage a Baby.

Pre-baby dogs are often showered with affection, toys, and clothing in extreme cases.

Pre-baby dogs are also usually the preferred topic of conversation amongst these newly-weds. They are often included (inappropriately) in social functions, on vacations, on Christmas cards, and on restaurant patios.

Many pre-baby dogs spend their days at "doggie day care", pet ranches, or have arranged play dates with other pre-baby dogs.
Have you seen Delilah and Ryan's pre-baby Dog, Jaxon? They can't shut up about him. It's rather off-putting.
