Does the Cougar Jerrv crews use dogs also in their works? Can you put a dog inside the Cougar in that case?
Maybe someone knows here?

Most of the MWD teams I saw in Iraq had their own HMMWV, however the dog and its' handler also went with what ever unit they were working with and rode in their vehicles. I can only speak for what I saw in a grunt unit. It might have happened, especially if EOD was going as part of a raid on an IED factory and they had open seats in their vehicle.
