My Shih Tzu doesn’t bark. Is it ok?

Hello everyone. My Shih Tzu is almost 7 months old. Got a spay last week and she’s so much better now :)

Idk if it’s because my wife and I did a good job, but Ivy never barks at random dogs or people, she’s friendly and sees it as positive, tries to communicate always and say hi.

The only situation she barks is when she plays with our neighbor dog, going crazy running after him and then give a bark or 2. Not something consistent. It’s probably her way of releasing energy during play.

If she wants to go out to pee or anything else she’d cry, never barks
