IT'S A FOX-TERRIER THING..

When meals are moments away, Millie starts bouncing.
She doesn't stop until Mum manages to put her bowl down onto the floor.
We got Millie when she was 6, and she was already a bouncer.
Mum's tried to encourage her not to, for fear she may damage herself, but she won't stop.

We'll just have to hope that she only does it because she enjoys it.
Just like her dinner.
