The best Arson Dog I've seen is a lab.
Truly a marvel to watch her work.
When she's off duty she's as friendly as can be.
No one is allowed to feed the dog except her handler.
She's friendly as a puppy when she's just hanging around, but when she goes up to the line to do a retrieve, she is all business, and when you give her the word she takes off like a rocket.
There she goes!
