Upcoming DC Universe film Supergirl contains scenes that may be difficult for animal lovers to watch, particularly those involving the character Krypto.

The movie's plot centers on Kara's mission to save her superpowered dog, Krypto, who is poisoned by Krem of the Yellow Hills, the leader of a space pirate crew known as the Brigands. This poisoning serves as the inciting incident for Kara's quest for revenge across the galaxy.

While Krypto is central to the narrative, his on-screen presence is less than might be expected. Early segments depict Kara and Krypto enjoying themselves on alien worlds, where Kara's powers are diminished due to the absence of a yellow sun, making her susceptible to alcohol. Their lighthearted interactions take a turn when Krem attempts to steal Kara's ship. Krypto intervenes and is struck by a poisoned dart. The actual moment of being shot is brief and can be anticipated, allowing viewers to look away.

However, the subsequent scenes depicting Krypto's suffering from the poison are described as lengthy. Kara brings Krypto to a local healer, who explains that the poison is an interrogation tactic used by the Brigands. They offer an antidote only in exchange for information, prompting Kara's pursuit of Krem to retrieve it.

While the depiction of Krypto's pain may be intense, the film reportedly does not reach the levels of animal suffering seen in other media. Krypto's declining health acts as a constant concern for Kara throughout the movie, but the narrative avoids showing him in a state of active dying for extended periods. The film includes a poignant scene where Kara fears she may not be able to reach Krypto in time to say goodbye, but overall, the on-screen depiction of dog suffering is considered relatively light. Viewers are advised to be prepared for a couple of scenes that might be emotionally challenging, though they are likely to be able to watch the film to its conclusion.

For those concerned about the ultimate fate of the canine character, Krypto does survive. Kara successfully obtains the antidote and saves him.
