Kotarou is the same as well. Since Kotarou is a sport dog breed, she is more trained to follow orders and do more physical labor than other things. Naturally, she has some level of intelligence since she has a light duty workdog license and a police dog license as well. If you had to order the anthropets in terms of intelligence, I think it would be something like (From smartest to not so smart):
Kuu > Kaie* > Mikan > Kotarou > Silvie
Anyhow, It just means that Kotarou won't be a scholar lol, but in my case I wouldn't want Kotarou to be a scholar, I want her to be herself, a cute working doggie whose innocence and attitude defines her personality.
It's really hard to accept that Kotarou isn't on their level, but when faced with facts like this, *sobs*
But I definitely agree on your last line "cute working doggie whose innocence and attitude defines her personality."
Yup, that's the insanely cute Kotarou alright.
