It's a bird! It's a plane! No, it's us!

We utilize friendly dogs that've been trained to detect a wide variety of controlled substances

The dogs are trained to produce a final passive response by sitting when they detect a trained odor.  This ensures they will not damage property, thereby limiting any potential liability to articles inspected.

All dog and handler teams are certified

No lockdowns are required during inspections

Our dogs are trained to work throughout daily activities


Non-intrusive but effectively visible.

  • Marijuana

  • Heroin

  • Cocaine

  • Methamphetamine

  • Alcoholic beverages

  • Commonly abused medications

  • Gunpowder

  • Ammunition

  • Firearms

Our dogs' core focus


"On April 28, 2022, at approximately 8:30 am, I was notified by our assistant principal of an unknown substance brought to her in the form of three white, round unmarked tablets. After making a sweep of the school bus where they were found, I discovered a fair number of these weird tablets in an empty cookie bag stuffed in a bus seat. I called lnterquest to request an emergency sweep of all our buses. Thanks to the quick response I received from Amy, the lnterquest scheduler, a canine team soon arrived to complete a thorough search. The pups saved the day!"

"As one of the security supervisors for Arlington Independent School District, I have had the pleasure of working with Interquest Detection Canine Service since 2002. Interquest has provided our school district with the most professional service."

"Thank you so much for the excellent support and service your handlers and canines have provided our school district over the past few years. This past week has been an exceptionally difficult one for our school district and we were forced to request Interquest make three unscheduled campus visits. Your company quickly altered your set schedule to respond to our needs almost immediately. This was completely unexpected, above and beyond any of our expectations."
