What types of trained animals help establish probable cause?

• A. Drug and bomb K9
• B. Guard dogs
• C. Search and rescue dogs
• D. Therapy dogs

Answer: (A)

Trained detection dogs are used because their trained alerts to specific substances are treated as evidence of contraband, which can establish probable cause for a search or seizure. Drug and bomb detection dogs are specifically trained to indicate the presence of illegal drugs or explosives, so their alert provides a basis to believe contraband is present. Other types of trained dogs serve different purposes: guard dogs focus on protecting property and deterring threats, not detecting contraband; search-and-rescue dogs locate missing persons; therapy dogs are there to provide comfort. Thus, the animals that help establish probable cause for searches are the drug and bomb detection K9s.
