Model input

User/Human

Who does "he" refer to in the last sentence? Only return the name.

Tom and Jerry were playing in the yard. Spike, the dog, was watching them from his kennel. Suddenly, he started barking loudly.

Model response

Spike 

The pronoun "he" in the final sentence refers to the most recently mentioned male entity who is capable of barking: Spike (the dog). The preceding sentence establishes Spike as the watcher in his kennel, making him the clear antecedent; Tom and Jerry are not described as barking.
