Personally, I think this belongs in the "Romper Room".
There is a reason for the CMF 18 series. It was to eliminate all of the extra support personnel from carrying the SF qualification. There has been use for dogs in the past and just like then if the need arises a dog and handler will be ATTACHED for the duration of the need. The same as for SIGINT, CCT etc.
Besides they don't have berets to fit pooches.
