IIRC, there are only 2 good bomb dog schools in the country. Lackland AF base and Philly K9 Acadamy. Do you know if they're keeping up with demand?
They keep up with federal demands, but from my experience, most local and state LE buy their dogs local kennels who import the dogs from Europe already trained to standard.
Lackland and Philly do their share also, and supply a big demand.
