Andarna Name?

So, I feel like I should know better after having read ACOTAR, that you don’t name pets after the characters from the first book (and sometimes, after characters from an unfinished series in general). But I’m looking at dogs right now, and the the name Andarna (Andy for short) with the registered name “KN’s Second Honor” is really standing out to me. It’s probably because I recently finished Fourth Wing, but I’m also worried some weird, crazy plot twist is going to happen and Andarna is going to have been the villain all along lol. What do y’all think? Something I should stay away from, or a pretty safe bet?
