Is it normal for my puppy's jaw to shake when excited or playing?

Pet's info: Dog | Miniature American Shepherd | Female | spayed | 6 months and 28 days old | 7 lbs

I noticed today while playing tug of war and fetch with my puppy that he mouth was shaking (to be more precise her bottom jaw). This was happening while she is waiting for me to thrown her toy so she can catch it. I wanted to know if it's something I should worry about?

This is likely just because she was really excited to be playing so I would not be too concerned. If she continues to shake her bottom jaw even when y’all are not playing then I would have your vet take a look at her. I hope this helps!
