I think they’re fine; the strong KYE sound of [name_f]Kaia[/name_f] makes them distinctive.
[name_f][/name_f][name_f][/name_f]I would think of the singer tbh -I guess you’d have to decide whether that bothers you or not. It’s a sweet name, but I do think you might get ‘like the singer?’ comments sometimes.
[name_f][/name_f][name_f][/name_f]Considering its current popularity, I don’t think it’s too much of dog name at all!
[name_f][/name_f][name_f]Kaia[/name_f] [name_f]Pearl[/name_f] and [name_f]Luna[/name_f] [name_f]Pearl[/name_f] would be my favourite options!
