Talk to fellow K-9 professionals. But remember that even though testimonials from other officers are always interesting, you should take them with a grain of salt. Talk to more than one department or handler. See if they agree on certain vendors or if their criticisms of providers coincide. The Internet can also be a great research tool; however, it should not be your sole source. Look for a vendor who has demonstrated experience training and placing police canines.
Demand quick response to an inquiry. How quickly a vendor responds to your request for information can be a good indicator of how that vendor will handle customer service. What the vendor tells you about its services and technical expertise will provide you with a good picture of its experience and professionalism. Does the vendor truly understand your exact needs?
Make some kennel visits. Visiting a prospective vendor is vital. When you get there, take a good look at the kennel, the grounds, and the offices. Are they clean? Are the dogs provided with quality care? Are the training grounds adequate? If the vendor is reluctant to show you around the entire facility, be ready to walk away.
Communicate your requirements. Ensure the vendor understands exactly what capabilities you need. Ask to see several dogs, not just the ones the vendor thinks best fit your requirements. By doing this, you will know the animals you are being shown are not "demo dogs" that are used just for show.
Ask for documentation. Ask for the canine's import papers, breeding paperwork, training, and health records. Get all guarantees and warranties on the canine's health and training in writing. Do not accept assurances that all the papers are in order; read and understand everything before you sign on the dotted line.
