Sure do Richard - it's Ketchum - all black and the biggest of the three - I swear he borrow's Harry Potter's Cloak of Invisibility!!
Just like you - we can search and search - calling his name, rattling the treat can - no Ketchum and retracing steps he's suddenly there right in front of us - looking 'Well c'mon with the treats then I've been waiting - ages!!' I wish I knew how he does this - it's quite eerie at times!
