Answer:
Personification.
Step-by-step explanation:
The personification is a figure of speech that consists of allowing inanimate objects or animals to have human characteristics. In this case, we can see an example of personification in the text presented in the question above, in the clause "webs of suspicion from the dog's mind." This is because "suspicion" is a characteristic feeling of human beings and not of animals. So when the narrator claims that the dog had webs of suspicion in his mind, it means that the narrator is making use of the personification.
