Ok, first up, security with dogs have been around the Valley and Brunwick St. Station for ages. They're pretty easy to identify: security uniforms and the dogs are the usual security breeds (German sheppards, dobermans & rottweilers).
Although I haven't seen them personally, I have heard that there are now occasionally drug sniffing dogs being taken through the area. As previously mentioned, if they are police dogs the handlers will be in blue police overalls. Also, not all police dogs are sniffers. I know here in QLD they use labradors and German short-haired pointers for passive-alert drug detection dogs. If you see one of these I'd suggest being concerned.
I suspect they are cracking down on Brisbanites - it
was and election promise, after all. Be careful and be sensible people. For upcoming events maybe do an inspection of the venue first to see what the situation is, then make a sensible decision about it. If you do definately see drug-detection dogs in Brisbane,
please post the details in the thread for that event and in here. But make sure you are certain and can provide a description. As it stands, this thread is just rumour really, and doesn't help anyone. Remember, we should all take precautions, dogs or not: you never know what could happen. Even without dogs plainclothes police are patrolling in the Valley and conducting spot searches on event nights.
Be safe!
