As Sunna say's trying to remain stealthy with dogs in your party is going to be difficult and may just invite unwanted attention from people considering the dog as food who may otherwise have wandered by without giving your bug in a second look,Don't get me wrong as I think dogs would be a great asset if you were being overt.
