>Wonder if the city plans to file suit against the kennel? Trained police dogs are very valuable.<
Dogs with a lot of "drive" (read that hyperactivity) tend toward a syndrome that causes their body temperature to soar out of control. It's common in Belgian Malinois, but can also afflict German Shepherds. Police dogs are selected because of their drive to work (and to fight with a suspect). This is not a trait one would have in the average housepet.
It's not necessarily the fault of the kennel, if the dog became agitated, and went into hyperthermia. Boarding kennels are set up to handle pets as a rule, and many people are unaware of the hyperthermia syndrome that affects working shepherd-type dogs.
I think he probably became overheated on the trip home... not at the kennel.
Very interesting information, thanks!
