With a nose that is 700 times better than ours, a very good set of eyes, superlative hearing they would be a great asset to any front line troops and display utter loyalty to their handlers for just a pat and friendly word.
I agree with Gil having seen allot of what the deefers do via electronic media I know just how powerful they can be having owned a 40 kilo Doberman he once attacked a blue healer only because the little bugger got out of a choker chain the owner threatened to kill my dog to which I replied if you do not f off I will let him go and he will finish the job.
Nope the deefers do not complain at all and go without question besides on a cold night you have your own heated pillow.
