Last Thursday the Senate Committee on Homeland Insecurity held a hearing on DHS' canine programs.

Links to Statements and prepared testimony can be found here:

as well as video of the entire hearing.

This is one of those "feel good dog and pony show (minus the pony)" oversight hearings, not a "gotcha" hearing so nothing earthshaking (no acknowledgement of TSA explosives dogs also doing narcotics detection because it simply doesn't happen) although I found interesting some the veterinarian's testimony of gene pools and other challenges of procuring and training the dogs.
