Make the Dog Testify/Playing With

Basic Trope: The witness called to the stand is an animal or an inanimate object.
 * Played Straight: Tropey the Wonder Dog is called to the witness stand to testify.
 * Exaggerated: The witness in question is a goldfish in a bowl.
 * The witness is a water cooler. When asked a question, a bubble comes up through the cooler.
 * Downplayed: The witness in question is a talking parrot.
 * Inverted: A human being (or in fantasy-type settings, perhaps one of the Fair Folk) is called to testify.
 * The lawyers and judge are animals, while the witnesses are all human.
 * Justified: Tropey is a Talking Animal or Funny Animal and therefore can speak.
 * Tropey is called up by a Bunny Ears Lawyer who doesn't seem to know what he's doing, but actually does.
 * Subverted: Bob is called to the witness stand, and brings Tropey up there with him.
 * Double Subverted: But Bob is an interpreter for Tropey.
 * Deconstructed: This wouldn't hold up in any Real Life courtroom, and is usually done when the lawyer is getting desperate.
 * Reconstructed: The lawyer has done his homework, and only calls up material witnesses. Since Tropey is a material witness, and able to speak and reason, the lawyer is justified in calling him up to testify.
 * Alternatively, see "Defied"
 * Parodied: The witness called to the stand is Mr. Stilton...a wedge of cheese.
 * Lampshaded: "I now call Tropey the Wonder Dog as my next witness..."
 * Averted: Nothing that isn't human is called up to testify.
 * Enforced: "We need to liven up this comedic series' courtroom episode with some Courtroom Antics!"
 * Invoked: The case is getting desperate, and Bernie the Attorney's client is facing life in Prison.
 * Defied: Bernie knows that no one would take a dog seriously, and that a dog cannot legally testify (even if it does talk), and so calls only relevant human witnesses or experts and hopes for the best.
 * Discussed: "Did he just call the dog to testify?!"
 * Conversed: "That wouldn't hold up in any court. Well, OK, maybe in Ruritania."
 * Played For Laughs: Almost always is.
 * Played For Drama: Bernie's client is losing the case badly, despite being innocent; calling up Tropey is a desperate last-ditch tactic to turn the trial around.
