Part of the only reason I'm keeping she/her in my pronouns is because being called a good girl is heavenly and I don't know a gender neutral phrase that sounds as good :|
Have you considered you do not need to use those pronouns to be labelled as such? I do not care much for human labelling, but as far as I have been made aware, it is an option to still be called 'good girl' without being a girl specifically?

Hold on your onto something

...... Okay genuinely you might be right
Do not get too caught up with mere labels. Do what your heart desires. That is what matters most. :)

oh i know i know!!! good dog!!!!!

Okay wait actually your so right
