If peter grill is a morally corrupted offensive NTR piece and futoku no guild is depraved animal pron, then yes this is a dog x woman romance or dog x woman fanservice. Seriously, this is nothing but completely self aware comedy that pokes fun at the scenario of our protagonist, the dog named rin tin tin (google this name btw), being into his owner, a high school girl named chika. Infact, there is less animal or beast related fanservice here than to love ru (maron) or futoku no guild. The shows starts with rin tin tin creeping near the bed of his owner chika to geta pantyshot, which doesn't work out as chika wakes up and whacks the bejesus out of doggy and he goes running for his life and tumbling down the stairs. The next scene moves to chika taking a bath and a frustrated rin tin tin imagining giving chika a backwash with a comical scene portraying that in his imagination " *hah hah doggo pant* wh-when we get married i'll give chika a back wash everyday *more desperate and bothered doggo pants*" All done in a hilariously self aware way.

Another scene after goes like this where they're all sitting around a dinner table:
Chika's mom: Did rin tin tin wake you up again?
Chika: Ugh this dog never leaves me alone
*rin tin tin scoots over to her chair*
Chika's mom (with a beaming smile): That's a man in love for you. You make such a nice couple.
Chika's dad( his face buried in newspaper): That's what happens when you live together, nature may as well take its course.
Chika than pops a vein in anger at the bizzare suggestion and rin tin tin is surprised and falls over.

The dog, rin tin tin, being into chika is played for humorous scenarios like getting embarrassed in front of her friends, a guy she's crushing on getting a wrong idea about her and the dog's relationship, the guy wrongly thinking she's suicidal in one scene and in another after seeing her with the dog in a faux compromising situation he remarks, "so that's why she wanted to suicide".

However rin tin tin doesn't ever come across as despicable or degenerate enough to ruin the show and offend one's sensibilities, seriously the dog seems more cultured that issei from highschool DxD as he doesn't have some creepy fixation on a single body part and that it's a thoroughly comical work. In one of the scenarios, chika's teacher is trying to get together with her in sneaky ways in a test of courage and rin tin tin tags along to foil his plans . In the middle of this, snakes come out that bite all of rin tin tin, chika, and the teacher but as the teacher panics and runs leaving her behind, rin tin tin stays with her.

it has a charismatic main character and is funny and ridiculous enough that by the end you'd almost think, fuck it, rin tin tin deserves to get together with his owner, gotta root for him even though the author never shows any intentions of going that route. That is precisely because it doesn't ever get too realistic to be uncomfortable. Its misfortune is that came out at the wrong time, got seen by the wrong audience of the times who got the wrong idea about it, and is niche enough that it never reaches the audience that would appreciate it for what it really is and what it actually tried to do.

An 8/10 because this show deserves so much better.
