Argos is our Chief Canine Officer (CCO), a lively 2.5-year-old with a colorful past. During his early years, he lived through a toughening spell as a street dog in Hungary, where he had to fend for himself before finding his way to Switzerland. In his new household, alongside two other dogs, he has finally found contentment. He’s a canine chameleon, mastering commands (in Swiss German despite the Hungarian background!) like a pro and showcasing his inner cat indoors – lap-seeking, sofa-snuggling, and the ultimate couch potato during TV time!

With a keen killer instinct outdoors, he’s been responsible for the untimely demise 💀 of approximately 12 mice 🐁 (and counting!), one bird, and several other smaller creatures since joining us.

He loves tearing around at full speed and has a particular fondness for car rides. He’s also a people person, enjoying the company of humans. He frequently visits our office, where he fulfils a wide array of functions, from access control to general comforting.
