Highway Patrol PSD Unit
The South Dakota Highway Patrol's Police Service Dog (PSD) Unit is an indispensable asset to the crime fighting efforts of all South Dakota law enforcement agencies. Formed in 1991, this Unit has grown to 12 teams and is responsible for intercepting millions of dollars worth of illegal drugs, confiscating millions in currency, weapons and vehicles, tracking individuals and locating key pieces of evidence.
The dogs are primarily Belgian Malinois. Each is paired with a designated handler, working and training in:
- Narcotics detection
- Explosive detection
- Criminal apprehension
- Evidence recovery
PSD Training & Specializations
Narcotics Detection Dogs
Narcotics Detection Dog Teams complete approximately seven weeks of initial training, then work to seek out drug couriers, assist local law enforcement agencies, search for illegal drugs in schools, sniff suspicious packages through the mail and help in educating others about the dangers of drug use.
Upon completing approximately seven weeks of Detection School training, Patrol Dog Teams attend an additional six weeks of training. In addition to drug detection, these dogs are trained in tracking and criminal apprehension and are used as an alternative to placing Troopers in unusually dangerous situations.
Explosive Detection Dogs
Explosive Detection Teams attend eight weeks of initial training, learning to find the odor of a variety of components that could be assembled into any type of bomb. This team responds to bomb threats and provides protective sweeps of the State Capitol and other State buildings in Pierre, along with sweeps prior to special events or the visit of dignitaries.
PSD Unit Teams
All dogs in the PSD Unit live at home with their handler and become part of the handler’s family, but they must be ready to go to work at a moment's notice. As the dogs become accustomed to the rigors of law enforcement work, they look forward to the challenges presented to them each day.
