A top notch office dog, he ensures that during our workshops we are not molested by cats or mice so that we can fully concentrate on the future of Previse Systems. During our occasional hikes, he keeps us entertained by encouraging us to throw pine cones for him to fetch – a game that he can enjoy for hours.

Usi lives in the Zurich area of Switzerland with his owners (whom he likes a lot) and some other dogs (that he does not care for much).
