I think it has more to do with the type of family and home a person has...but of course personal preference plays a role too. I was referring to police officers, a few K9 officers, a few police dog trainers two that provide k9 certification program instructors...one of which is former french ring II certified decoy as well as a private security contractor...one with some government contracts that tends to do some k9 based contract work overseas for other parties (training police k9 instructors), and the other has had some VERY large government contracts in the middle east.
