I got my DVD of Barking Dogs Never Bite from MachiavelDVD.com, its a Canadian site.  The DVD is Region 3 NTSC.  Cost was $22.15.  It is available also at HKFlix.com and YesAsia.com, cheaper than MachiavelDVD.com.  I got it from MachiavelDVD, since I like Marc the owner of the site, I don't mind spending a few extra bucks.
