No. While Sythe is an Anthropomorphic animal he isn't an animal in the sense of a dog or a wolf from our world.For it to be Zoophilia the creature in question must be an actual animal. Anthro animals are just like people in that they are sentient and sapient, they are aware of themselves as individuals, aware of their own ego and that their actions have consequences.In the comic Sythe asked Maren if she wanted to hook up and in his room he recognized that she was still flustered and nervous and while willing she was still unsure and questioning herself. He made it clear from the outset that he wasn't pressuring her and that she could back out any time that she wanted and that hooking up would just be a way to explore and feel things out. See what it is that Trace and Flora are so keen on.An animal on the other hand would not have done any of that. An animal would have just shoved his nose into here and there on Maren, making her flustered and uncomfortable and would have probably tried mounting her there and then at the pool in front of everyone.If you aren't sure if something is Zoophilia or not give it the Harkness Test of Fuckability - imgur.com/gallery/6jp4DVK
