Cooper plays a rock star who returns to his hometown, which has been plagued by wild dog attacks.

Vince Raven (Cooper) is performing in the music video for his new song, "Identity Crisis."

The crew cannot stand to watch it suffer in pain, so Vince puts it to rest by killing it with a large rock.

Vince and Sandra chase after him to get him to a hospital, but the Monster Dog scares them back into the van.

The next day, the crew decides to begin filming their next music video for Vince's song, "See Me in The Mirror".

As Angela walks down the stairs, she notices the shadow of a body that is resting against the upstairs window.

As they drive off, Marilou's corpse falls on Sandra and the Monster Dog attacks Vince from the back seat.

In the 1980s, he often worked with Bruno Mattei as an uncredited co-director on women in prison films and gory horror movies.

Fragasso and his wife Rossella Drudi then wrote a script influenced by An American Werewolf in London and The Howling.

[2] In an interview several months after the film's initial video release, he said that he had selected Monster Dog from numerous scripts submitted to him because "I didn't want to do a heavy-budget movie.

[3] In 2012, he noted that he had agreed to do the film soon after completing treatment for alcoholism, "and I really wanted to see if I could work sober."

[4] Line producer Carlos Aured spoke positively of Cooper, who he said had only two requests: a supply of cold Coca-Cola, and a VCR in his room so he could watch old Westerns.

[2] Vera would recall the film as "wretched and unpleasant, but I had a tremendous time together with Alice; he is a very fabulous and funny person.

The movie was shot back-to back with another horror feature, The Falling, in Torrelodones, Spain.

The monster's head, a large puppet, broke in the first scene in which it was used, resulting in part of the script being rewritten to work around the prop's lack of functionality.

[8] Fragasso claimed that Sarlui had edited the movie without his involvement, and that about 20 minutes had been cut, including the best scenes; he asserted that "what has circulated on VHS and DVD is not the film that I shot."

[11] It was released theatrically by Union Films S.A. on August 16, 1988, in Spain,[12] where it sold 53,438 tickets and grossed an amount equivalent to €151,303 in 2023.
