Tibetan throat singing

Britta has developed a new habit, and it's slightly disturbing: it's a raspy growl that I refer to as Tibetan throat singing. I am not sure if it is because Britta is mimicking all the "guard" labra-doodles the neighbour has, or because I make a growl when I pick her up and tickle her tum.

Britta has two teeth already and more are sure to follow.
