((((((NOVEL SPOILER))))))
here's one bit of the novel where a dog is mentioned:
Sawol buried its nose in the wide-open cleft, sniffing, and, as if already accustomed, naturally extended its tongue to lick broadly. Realizing honey was leaking from the twitching hole, the dog tried to push its tongue inside.
“...—Hnng.”
this is just one bit of it. it gets worse btw. please do not read this if you cannot handle these topics.
