LOL, I was talking to my buddy up here at work who is a part time dispatcher. Two of the Dogs one was Athos (retired who I know) and from what he understood, Drago were Check trained. I’m unsure about the other two.
I believe that Plum’s dog is Hungarian (saw a demo last summer at my soon to be step daughter’s summer camp)
Regardless, the comment I quoted from the poster is wrong that all dogs are german trained and take commands only.
