The announcement of the name was met with some criticism due to the word "chupa" being a slang term for fellatio in Spanish and Filipino.
Although it's been appropriated by Mexicans, the chupacabra actually originated in Puerto Rico and it's only after it was popularized there that it began to spread to other places.
Filming took place in multiple locations throughout New Mexico starting in August and running through October 2021.
They used a real dog on the set as a stand in for Chupa. This was because the filmmakers thought its better with a real animal than just a puppet to act with. The dogs name is Harper. Its not stated what kind of dog Harper was.
